30mA RCD protection required for existing circuit?

[spud1]

If I was replacing an existing light fitting in a domestic premises, making no alteration or addition to the circuitry, would I then be obligated to provide that circuit with 30mA RCD protection if it didn't already have it?

If it’s a “like for like” swap, then there’s no need to install an RCD, but you could just mention it to the customer and explain it would increase the safety of the circuit inline with the current regs.

I would say that you only need to provide the RCD protection, if you are extending or altering the circuit.

Like for like then no, but I would inform the customer of regulatory changes and allow them to make a decision ad make a note of that on the MWC.

Would you issue a Minor works cert for a like for like light fitting replacement!?

I know some on here do, and BS7671 suggest this is a suitable use of a MW, but personally I think its just a waste of trees. A Zs test result could go on the invoice.

I think the purpose of the regulation is that this is a job that is highly likely done by the householder or DIY'er and therefore gives increased protection. I think that it applies to new and rewired domestic lighting circuits for when the householder goes to change a standard pendant fitting to a decorative one. For RCD protection to be required on an existing installation when the householder wants to change a fitting would be costly and in most cases impractical. And in this case, the risk is reduced as it is done correctly by someone engaged that is competent.

Yes as I would carry out basic inspection and testing to ensure the circuit is safe and fit for continued use.

Fair enough, when replacing accessories or light fittings like for like, I usually make a note of a Zs and or any RCD test readings etc. where applicable on the job sheet for my reference, I don't normally go as far as issuing a MWC to the client but maybe I should start...?

The 18th edition MEIWCs require a lot more information than they used to.

Completely up to you. Either method suits as all the client will do is shove it a drawer and forget about it.

I don't think many customers would give a stuff about a MW cert for a pi$$y --- little job, 15 minutes to put up the B&Q special, and another half an hour to gather the plethora of info now needed for a MW.
"That bit of paper is going to cost you another 20 quid labour Sir, that OK? Just chuck it in the bin when I've gone."

Everyone gets a MWC, why wouldn't you? Just approach every job with the line, if it wasn't written down it didn't happen!

How would you do that if you are mot changing it to a dual RCD split one?
Unless if you fit an RCCBO on that cct.
What would you do with the other ccts in the board wjich are not RCD protected?
Sorry for the rant but you don't have to.
