To avoid electrical shock, RCD automatic devices are installed - if the differential current is greater than the authorized limits, they cut off the load. Therefore, it's critical to pick the proper residual current device and connect it correctly. But, again, this is a job for a professional electrician.

Electricity is divided into functional blocks. Low voltage (5V or under) is limited to small appliances. They don't require unique installations, but the cables mustn't be too long, and they must fulfill some general safety rules.

Residential electrical plugs are beneficial for hair driers, tea kettles, vacuum cleaners, etc.

Tools are used for different tasks, e.g., woodworking or metalworking require higher voltage six-under to operate. The devices are constructed so that an amateur can handle them without creating too much risk of faults - the cables are big enough to avoid cable breakage during work. It's still required to connect the tools to the wall socket with a line.

The voltage between 220 and 240 is used for large machines, e.g., air conditioners. The power cables should be protected against mechanical damage by using armoured wires - they should also be secured at two or three spots against falling or other types of damage (e.g., drilling a hole). By abiding by the rules, one limits the risk of fire.

The main thing to keep in mind is that it's dangerous to allow children or inadvertent users to use tools independently. Also, special care must be devoted when one uses extension cables - they can't be overloaded and have to be plugged directly into a socket without using a multi-outlet strip.

In the event of an electrical fault, it's necessary to know what to do. All electricians have training in first aid and rescue operations for house accidents. In case of a blackout, one should wait for about half an hour before going on their way home - specialists say that a power cut doesn't immediately mean that the power supply was lost; it can also take place if a line is overloaded.

We offer you two brief safety instructions for basic electrical installations:

1. Before starting any work on your home electric machinery or equipment, always turn off the electricity at the main switchboard. This way, you'll avoid accidents or injuries because of electric shock.

2. Electric cables are supplied with different voltages, so it's advisable not to use one line for more than one device because by doing so, you risk getting an electric shock. If you have any doubts about the type of electrical installation in your home, contact a professional electrician to help you out with the installation.

There are marks indicating the neutral wire and phase terminals on each device. It is essential to follow these directions precisely. It's also crucial not to modify the entry and exit positions. The input machine's wires should be connected to the input, while the load should be connected to the output for the operation to succeed. If you relocate it, there's a risk of false triggering or total device failure.

If you do this job, ensure the residual current flows correctly and without any trouble. If the machine is moved, it's necessary to connect a cluster of safety devices used for preventive and protective purposes. Only persons authorized by our company should install them.

Features of the installation of RCDs and machines

After installation, RCDs are mounted on a DIN rail in the usual electrical panel. It's critical to note that the gadget only works with leaks, not short circuits. As a result, you must install an automatic switch in conjunction with the RCD and connect it ahead of the device.

Behind the house appliances, the RCD is installed. Install them in locations other than bathrooms, shower cabins, and other damp areas.

It's typical to place an information sticker on each device that shows the symbols for the electric wires connected to it, along with their voltage and phase. Before you install, double-check that the colour coding is correct. It's possible that the colour code on your phone varies from one device model to another or that manufacturers change it without warning.

Remove the power and test each electric connection when you're done with the construction work. Check for any exposed live components like screws or metal craftworks before turning the electricity back on.

To secure yourself long-term against fire risk, you'll need to keep track of your utility expenditure and compare it with the market average.

If many household devices are present, the following procedure should be followed: first, an introductory machine with an electric meter - 100-300 mA RCD for public safety - then 10-30 m A RCD for private consumers.

Do you require an electrician to install RCD devices? You can locate a competent electrician on the Geolance website that is not only safe but also lucrative. Picking a supplier based on evaluations and ratings, as well as negotiating the price of the service yourself, is possible.

Phase conductor: green wire

Neutral conductor: blue wire

Earth: green and yellow striped wire or a green wire with a yellow stripe

Phase: 3-phase power or 1-phase wye (3 wires)

High voltage: three-phase four-wire, square wye (5 wires), single phase 5 wire and so on.

Voltage: 220-240 V single-phase. 440-480 V for 3-phase electric machines

Different types of equipment need different voltages. It's crucial not to confuse the cable with power because lines operate on different voltage levels. If you're in doubt, call an electrician.

How much does it cost to install RCDs?

The price of installing one or multiple RCDs varies depending on the size and type of your home.

In cases where the electrician is obliged by law to enter your home, they must consider all expenses incurred during its visit.

How much does it cost for an electrician to install a circuit breaker?

For homes with several socket extensions, you might need a circuit breaker instead of an RCD. Although these are similar devices, circuit breakers are slightly more complicated to install.

The total cost of installing a breaker varies depending on the number of sockets, size, and time for an electrician to perform the installation.

Functions of RCDs and the ways they work

RCDs work by sensing imbalance in the current running through them. The input has three conductors: phase, neutral, and ground. There must be a leakage in case of a difference between the current running through the phase conductor and that in the neutral wire.

Right now, residual currents are too high for them to cut off power quickly enough to prevent incidents or injury. Nonetheless, this safety gadget is an essential addition because it's necessary to implement an effort to solve electrical accidents before they take place.

The electrician's visit is the best time to install RCDs. However, it's possible to locate a professional on the website Geolance, where an evaluation and rating system follows each service you book. You can also negotiate your price for services with suppliers.

To keep track of utility costs and compare with market averages, you need an efficient source of energy that is safe from fire risk. For this reason, you'll need electrical RCDs installed as well as a circuit breaker for your outlets.

The cost of installing RCDs varies depending on the number and type of electric connections in your home. Depending on where your electrical problem is and how many RCDs you need, the installation price can be negotiated with an electrician.

A three-phase network is another crucial element.

It's essential to install an entire system, which is the only way to ensure that your devices are safe. As far as possible, follow instructions for the device to supply power adequately. The wrong input could cause false triggering or complete failure of the RCD. You should also never relocate it once installed, or there is a risk of triggering false triggers or complete device failure.

The best time to install an RCD is during the electrician's visit. You can also contact one on Geolance, where you'll receive your service, followed by evaluations and ratings from customers, as well as the opportunity to set your price. Never use low-quality equipment, as it could cause false triggering or complete device failure.

Residual current devices

The residual current device is electronic hardware that is used to protect people from electric injuries. It is usually professionally installed by a qualified electrician in homes, schools, hospitals, or other buildings with electrical appliances. Unlike an ordinary circuit breaker, an RCD does not switch off the entire mains supply but only disconnects the faulty machine, keeping people safe.

The primary purpose of an RCD is to provide a safety device for the people. When it detects a fault, it switches off automatically. In the case of a non-fault condition, there is no electricity leakage, and the circuit remains live. However, residual current devices are not designed to protect electrical equipment from overloads.

When choosing an RCD, it is essential to know the maximum current to operate on a circuit. The RCD should be matched with this value if it is to perform correctly. This means that if the devices such as power tools and kettles are used individually, different types may need to be installed to accommodate them all.

Another essential factor to consider is the number of RCDs required for a particular installation. It may be convenient to have only one device controlling all circuits, but this can lead to safety problems if someone using a faulty appliance accidentally re-establishes the course with another machine. This can happen in cases where devices are plugged into extension leads.

The installation cost is usually calculated based on the number, type and location of the appliances that need to be protected. For example, additional RCDs will need to be installed if you run an electrical device off a generator or solar panel system in addition to the mains supply.

Tips for proper use

- Never install your residual current device. These devices are designed and tested by professionals to ensure the safety of you and your family. If it is not established correctly, there is a risk of electric shock and fatal accidents.

- When using an RCD on a circuit where three or more appliances are plugged in, make sure they all have their RCDs.

Basic types

There are two main types of RCDs: - Type B (older power outlets) - Type A (newer ones); both are widely used for residential purposes. The difference is that type A can also be fitted with an earthing plug, which allows you to revert to standard mains if the fault condition is removed.

Basic features of RCDs

An RCD is fitted with a test button that allows the user to check whether it works correctly. The device has its indicator light showing any fault, which will remain on even when the electricity supply is disconnected. Most RCDs are also equipped with an Earth wire connection called SPD. It means that all equipment with this connection is not switched off in the event of a fault. Some RCDs have an additional equipment protection function called SSP - Supplementary Protective Device, which allows you to keep appliances such as washing machines and ovens safe from overloading.

How does it work?

An RCD works by measuring the difference in current between the live and neutral wires. If the devices connected to the mains exceed a certain threshold, for example, 5A or 10A, then it switches off immediately to protect against electric shock.

An RCD features a re-settable circuit breaker with a trip time of 0.2 seconds maximum. Once the circuit appears to be usually working, the re-settable feature triggers the RCD to switch on again. A device such as a washing machine will not activate an RCD because it does not require more than 10A of current to start up.

Installation rules

Before installing your new or replacement residual current devices, you must ensure no power cables to be cut or joined. If it is necessary, you should contact an electrician before installation takes place.

When deciding on the location of your new RCDs, you should check that all sockets are within easy reach and that they can accommodate large plugs without blocking adjacent sockets. In addition, make that there is enough space to plug in two large appliances at once, such as a toaster and a kettle.


Types of protection

There are three levels of electrical safety: - personal (Type B) - supplementary (Type A) - public (Type B and Type A).

The first (personal) is used throughout the home, which means it must be installed behind every power outlet or double powerpoint. This type is intended for protecting people from accidents when leaving electrical appliances are switched on by mistake.

The second (supplementary) is installed in the bathroom, and the kitchen, where water might contact live components or electric shock can occur between various metal parts of a system. The supplementary level also protects people who are not familiar with electricity and may be in contact with it unexpectedly.

The final (public) is meant for use in public locations such as schools, hospitals and shopping centers where many people can be at risk. This system should comprise all the necessary equipment to protect everyone without disrupting usage or causing inconvenience.

I am choosing an RCD carefully.

Several safety factors should be considered when choosing the type of RCD device for your home.

First of all, it's necessary to establish what kind of circuits are likely to require protection. Each electrical circuit has two conductors (live and neutral) that must be identified before installing an RCD unit. For example, if you want to protect a water heater with a heating element, you should install an RCD with high-temperature protection. You can find out more detailed information on the Geolance website.

Secondly, one needs to determine the role of each circuit to create a complete picture of electrical safety. For instance, you might want to protect some appliances from short courses while others may need protection from overheating.

Finally, it's essential to choose the right type of RCD capable of protecting each appliance or circuit on its own. Thus, a kitchen and bathroom require supplementary protection as they contain potentially hazardous electrical equipment such as heaters.

Residual current circuit breaker type A

A residual current device (RCD) is a safety device that immediately disconnects the power supply to an electrical installation when it detects any unbalance in the electric current passing through its current-carrying conductors. This happens due to a difference between currents in live and neutral conductors, which should generally be equal. Unbalance is often due to a fault outside the installation that causes a current flow in the live conductor, from hot to neutral. Such an unwanted electric current may result from a severe defect such as a short circuit that would otherwise cause significant damage and injury. RCDs are more reliable than fuses or circuit breakers, as they do not require a fault to be detected before switching off the power.

This type of RCD works with a device that makes sure that both conductors have equal currents – this way, it can immediately determine the difference between current passing through hot and neutral lines, making malfunctions easier to spot. In other words, equipment won't be damaged by an overload.

There are three different ways of using residual current circuit breakers (RCD):

Tripping time

This type protects the device if there is a difference in the currents detected within 15 minutes on either side. If the difference continues, RCD turns off the power source and ensures no current goes through. As a result, the unit won't react to regular changes between hot and neutral currents.
