Electric showers require their own electrical circuit, which in general will have the highest electrical demand out of your household appliances. All circuits in a bathroom must be protected by a RCD (Residual Current Device).
Do lights need to be RCD protected?
“Regulation 411.3. 4 specifies that additional protection from a 30mA RCD is now required for all lighting circuits in domestic properties, without exception. Be aware, that this requirement for RCD protection for lights ONLY applies to domestic properties.
What needs to be protected by an RCD?
An RCD is designed to protect against the risks of electrocution and fire caused by earth faults. For example, if you cut through the cable when mowing the lawn and accidentally touched the exposed live wires or a faulty appliance overheats causing electric current to flow to earth.
Why do lights need RCD?
An RCD works by detecting leaks in electrical currents which may pose a risk of shock. For example, electrical currents are intended to travel through selected conduits for safe electrical power, and when there is a leak in that conduit, electrical power can be placed where it causes a shock hazard to people.
Does a shower need its own RCD?
No, the regulations do not specifically require showers to be on an RCD, however, the shower manufacturers (and most sparkies) consider that it is good practice to fit a 30mA RCD.
Do bathroom lights need to be earthed?
Bathroom ceiling lights, wall lights and downlights are all available without the need for an earth connection. Lightahome has actually specialised in these types of lights for years.
When can RCD be omitted?
For sockets not in 2-12 above and, not in a dwelling, RCD protection may be omitted if there is a documented formal Risk Assessment that determines RCD protection is not necessary.
Do all circuits have to be RCD protected 18th edition?
There is still an exception to omit RCD protection where, other than BA1, BA3 or children (BA2, BA3) and mobile equipment (not exceeding 32 A) for use outdoors, a suitably documented risk assessment determines that RCD protection is not necessary.
When did RCDs become mandatory?
Since 1 May 1984, RCDs are mandatory for all rooms with a bath tub or a shower. Since June 2007 Germany requires the use of RCDs with a trip current of no more than 30 mA on sockets rated up to 32 A which are for general use.
Do all socket outlets have to be RCD protected?
Unless the electrical installation designer is convinced that the socket-outlet cannot reasonably be expected to be used for other purposes, RCD protection for that socket-outlet should not be omitted. In the vast majority of cases, it should not be necessary to omit RCD protection for a socket-outlet.
Does a cooker circuit need RCD protection?
Only need to RCD-protect the cooker circuit if the cooker unit is a cooker switch of the type which incorporates a 13A socket. Otherwise there’s no need.
Can a consumer unit be in a bathroom?
Your consumer unit should be nowhere near a shower room. Get an Electrician in to advise you the builder saying boxing it in is totally wrong, you are not allowed to have a wall switch in a bathroom/shower room let alone a consumer unit!
Where is Zone 2 in a bathroom?
Zone 2 is the area stretching to 600mm outside of the bath or shower, be that above or to the sides of each. This is typically the area that is least likely to get wet but there is a possibility for it to be splashed.
Why do some light fittings have no earth?
If any of our lamps, lights or bulb holders do not have an earth connection it will be because the outer surface is predominately made from a non conductive material such as glass, plastic, ceramic or bakelite etc, therefor it is not necessary to earth the unit.
Can you wire a light with no earth?
A double insulated light, which is also known as a class 2 light, is designed in a way to allow fitting to your electrics without an earth connection. These types of lights are totally compliant & any decent electrician (who knows their current regulations) would have no problem in fitting them.
Do 32A sockets need RCD protection?
Under the new 18th Edition, all final circuits rated 32A or less need RCD protection to at least 30mA earth leakage. There is no exclusion for 3 phase circuits, so this will cover all 16-amp, 32 amp, single and three phase sockets.
Do all circuits need RCD protection EICR?
If the Electrical Installation Condition Report (EICR) is Satisfactory then you do not need to replace the consumer unit, even if it does not have RCD protection. RCDs are only required by law in new builds, additions/alterations or rewires.
Can you have 2 RCDs in a circuit?
Hi, I have two 30mA RCDs in series, first one as the main switch in the house consumer unit covering all 11 circuits, second one as the main switch on a garage consumer unit, covering three circuits.

Can I fitting an RCD to old fuse box?
Whilst it is possible to fit a separate RCD to the circuit or multiple RCD’s, if more than one circuit is being altered, by far and away the best and most cost effective solution is to have a new Dual RCD and MCB fuseboard fitted.
What is the difference between a circuit breaker and an RCD?
The difference between a circuit breaker and an RCD switch is the purpose of a circuit breaker is to protect the electrical systems and wiring in a home while the purpose of an RCD switch is to protect people from electrocution.
Do I need an RCD fuse box?
This is because an RCD is a very important part of a fusebox. Its purpose is to protect you from electric shocks and your property from electrical fires. It does this by constantly monitoring the electric circuits in your property for leaking current caused by earth faults.
What is a C3 on an EICR?
EICR C3 meaning
To be clear, no danger is present and there is no typical sequence of events that could lead to someone accessing live wires.
Is it illegal to do electrical work without a license UK?
A ‘non-qualified’ person can still carry out notifiable electrical work as long as Building Control are informed – but if you fail to do this and the work is found to be unsafe, it can lead to a hefty fine.
Do meter tails need RCD protection?
Do Buried Meter Tails Need RCD protection? It may sound odd, but the answer is yes, meter tails buried in walls, less than 50mm from the surface will require additional protection by 30mA RCD.
Do hardwired ovens need RCD?
No, the only requirements are: New circuit added to a switchboard are required to fitted with an RCD in domestic and as required in non-domestic/non-residential installations. All the circuit protection devices are replaced on a switchboard then all the circuits required to be RCD protected shall be RCD protected.
How many RCDs do I need?
Under the Electricity Regulations 1947 (the Regulations) all residential premises to be sold, rented or hired must have at least two RCDs protecting the final sub-circuits to socket outlets and lighting. There must be no more than three final sub-circuits per RCD.
Can a bathroom fan and light be on the same circuit?
You may have two switches but only need one switch to run the two. This process is not only possible but easy to achieve. It is not a bad idea to connect the bathroom fan and light in your home on the same switch. It is safe to operate both at the same time.
Do lights in a bathroom need to be GFCI protected?
As mentioned above, GFCI protection is required for any electrical outlets or switches that are in the area where you could get wet while using your bathroom. This includes the bathtub area, sink area, and shower stall.
Can you put a fuse board in a bathroom?
Can I have a consumer unit in my bathroom? According to regulations, electrical equipment should not be present in shower rooms or bathroom. This includes simple equipment such as wall switches, plugs and especially consumer units.
Can you have a fusebox in a bathroom?
The consumer unit (fuse box) would be fine as long as you can get to it from the hallway side and not from beside the toilet. Some careful thought on the toilet and waste, whether the waste pipe will exit under the toilet or out the back into the space where the electrics are.
What does Zone 1 and 2 mean in bathroom lighting?
The Zones. Zone 0: Lighting directly inside the bath or shower. Zone 1: Lighting directly above the bath or shower, up to 2.25 metres(m) from the floor. Zone 2: Lighting placed either side of the bath, shower or wash basin up to 600mm (0.6m) outside the perimeter of the water sources and up to 2.25m from the floor.

With IP65 downlights, your total light protection can be installed over your shower or bath without the danger of any possible safety issues (such as electrocution), something that can not be guaranteed with IP64 or less downlights.
Does a lighting circuit need an earth?
no you do not need a earth in a lighting circuit, but you can not have any metal fittings {switches are lights] they must all be plastic. Lighting circuits installed before 1966 often did not include a circuit protective conductor (cpc).
Do ceiling lights need to be grounded?
Strictly speaking, grounding your light fixtures isn’t necessary in all cases. However, it’s a good idea as it makes your light fixture safer and reduces the risk of injury. Metal light fixture boxes should always be grounded where you install the fixture.
Do GU10 downlights need to be earthed?
This is the same ring and connector plus socket GU10 arrangement that is widely used with halogen lamps. Answer: A class II or double insulated luminaire will have no provision or requirement for protective earthing since they are designed and constructed so that the exposed metal parts CANNOT become live.
Should a metal ceiling light be earthed?
1 Answer from a MyBuilder Electrician
If it is not double insulated then it should be earthed with an earth cable which connects the fitting to the means of earthing at the origin of the installation.
How do you tell if rooms are on the same circuit?
Plug the lamp into another outlet to determine whether or not that outlet is on the same circuit. If the lamp lights with the breaker still off, then the outlet is on a different circuit.
Can you rewire just upstairs?
Can You Rewire Just Upstairs? It is possible to rewire just upstairs and in many ways, this is easier than rewiring downstairs. The carpets and floorboards can be lifted to access the cable highways running below the floor, and the open loft space is used to crawl around in and access the lighting circuits.
Which circuits should be RCD protected?
RCD protection is required for socket outlets which could be presumed used for outside of the equipotential zones (i.e. outside, providing there is equipotential bonding within the home) this could include an extension lead used for a vacuum cleaner or pressure washer or any outside cables feeding sheds etc.
Is no RCD protection on lights a C2?
If any circuit does not have an RCD then this must be recorded as a C2 – POTENTIALLY DANGEROUS as an MCB or fuse will not trip in the required time leaving items potentially dangerously live.
How far does a hand dryer have to be away from a sink?
Leaving a horizontal distance of at least 60cm between dryers and baths, sinks, toilets and water sources is usually essential – as this diagram shows.
