Question: Do all lighting circuits need to be RCD protected?

“There is no regulatory requirement for a lighting circuit to be RCD protected, per se, but if there is any new wiring buried Do all electrical circuits need RCD protection?

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.

What circuits need an RCD?

Residual Current Devices (RCDs):

For non-residential, final sub-circuits up to 32A capacity supplying socket outlets must be 30mA RCD protected. Hard-wired equipment circuits of this capacity should be. All lighting final sub-circuits must be RCD protected.

Do bathroom lights need RCD protection?

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). They will need to be connected to the consumer unit and protected by an RCD.

What code has no RCD protection lighting?

The NICEIC electrician I used for my EICR has given me a code C2 for ‘no RCD protection to lighting circuits including bathroom lighting’.

Can I use an RCD as a main switch?

1 – can you use the RCD as a main switch for the installation – yes, all RCCB’s that meet BS EN 61008 are rated for isolation. 2 – should you be using a single front end RCD – again probably yes. BS 7671 imposes on a you a requirement to avoid danger and minimise inconvenience.

Can I use a 100mA RCD?

Because BS 7671 now requires it for increased safety in domestic premises. Quite simply, a 100mA RCD is not suitable for personal protection, check out the threshold for fibrillation. TThe manufacturer has specified a preference for it, but happy with 100mA.

Does a sub main need to be RCD protected?

A 100mA Timed RCD is used to supply a submain that is used to supply a consumer unit with 30mA RCD’s. Depending on the current installation and earthing arrangement, you may not need the timed RCD with any other provided earthing system.

What is a 30mA RCD?

‘High sensitivity’ RCDs, rated 30mA or even 10mA, are designed to disconnect the supply within 40ms at 150mA and within 300ms at rated tripping current to protect the user. ‘Medium sensitivity’ devices, rated 100mA or more will provide protection against fire risks but will not provide full personal protection.

Is no RCD a C1?

Obviously you consider RCD protection (additional protection) to socket circuits the most important possible difficulty with an installation, therefore a C1.

Is no RCD a fail on EICR?

EICR coding & what it means for your Landlord Report

When an inspection is completed, the lack of an RCD where now required by newer regulations would be highlighted. … An landlord electrical report can still be classed as SATISFACTORY even if the installation has a number of C3 issues.

Is no RCD on lights a C2?

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.
