Do all domestic circuits need RCD protection?
2. BS 7671 requires most if not all circuits in domestic premises to be RCD-protected. Separate RCD protection is not necessarily required for each circuit of an installation but, in order to minimize the likelihood and consequences of tripping, a single (‘front end’) RCD should not be used to protect all the circuits.
Where should RCD be placed?
Fixed RCDs These are installed in the consumer unit (fusebox) and can provide protection to individual or groups of circuits. A fixed RCD provides the highest level of protection as it protects all the wiring and the sockets on a circuit, and any connected appliances.
Do all circuits need RCD protection 18th edition?
411.3. 4 specifies that additional protection from a 30mA RCD is now required for all lighting circuits in domestic properties, without exception.
Is having no RCD protection 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.
Do outdoor sockets need RCD?
If you use any portable electrical appliances outdoors, they must be protected by a 30mA RCD. And if you use an existing indoor socket to power appliances outdoors and it doesn’t have RCD protection, you’ll have to use a plug-in RCD.
Does an RCD need an earth?
RCD does not necessarily require an earth connection itself (it monitors only the live and neutral). In addition it detects current flows to earth even in equipment without an earth of its own. This means that an RCD will continue to give shock protection in equipment that has a faulty earth.
Is no RCD a C3 or C2?
Is no RCD protection a C2 or C3?
The socket-outlet circuit appears to have no RCD protection; if the sockets are supplying equipment outside, this would be a C2, otherwise a C3.
