RCD fused spur

[ianphilip007]

Query regarding a Passive RCD fused spur unit protecting a bank of 4 led downlights supplied via switched live and nuetral. I have been asked to replace the downlights. Cant be totally sure but i think RCD spur was to protect the (addition)of the downlights. The rcd is passive so will remain latched when switched.

Not ideal I know but even if not required some RCD protection is better than none so don't really want to remove. Guess it's still working even with the switched supply

Not sure I agree, if additional protection is not required, then it serves no useful purpose. If you are leaving it in, why not correct the installation of it?

i have only been asked to replace the actual downlight fittings, don't think customer would be too happy with the added expense of altering the lighting circuit. my concern was with the rcd being on the switched side as it is not a standard arrangement but many thanks for your replies.

Perhaps if you explained the situation to the customer. Sounds like the existing install is either diy project or done by sparks who didn't know what he/she was doing. I'd be looking closely at what I was adding to.

Would definitely test circuit and have a good look first, would need MWC anyway.

Would not be making any addition only replacing the fittings for Led fiixtures. Thinking about the odd placing of the RCD I think it could have once been a elv downlight installation which has been converted to mains gu10 maybe the RCD fused connection unit was placed where the existing tx originally was to provide RCD compliance for the new lights. Would be an explanation.

As for the circuit all appears normal except for the RCD placement. Correct cable sizes for existing down lights, wago lighting boxes at each down light and even a 3 amp fuse in rcd fused connection unit not a 13amp as I expected
Though strange in my opinion I can't really see any problems with it if left and it is providing protection to the 4 lighting points

I don't see a problem with it either, I would still provide a Minor Works as proof for Regulation compliance.

totally agree but best to be covered.
