Hi I’m looking for advice on the following: I’ve yet to contact my local council about installing a light in Zone 1 of my bathroom (this due to height restrictions) but reading up on it in order to get ready for the off I thought it wise to check out my understanding / intentions first. The light will be a LED, 240v (built in driver), IP65, Class 1 fitting. For this I understand it’ll need to be protected by a 30ma RCD.
My question is as follows: My domestic consumer unit has a 100A, 30mA RCD main switch and the 2 x lighting circuits each have 6A MCBs. When I put the new light in I intend to take a feed off one of the lighting circuits (which has just 7 lights on it totalling about 120 watts) and run it via a passive fused spur box with a 30mA RCD built in and fitted with a 1 amp fuse. This will be located in studwork outside of the bathroom as will the on/off switch. This effectively means I’ll have 2 RCDs serving the light – 1 on the consumer unit mains in and another RCD on the lighting sub circuit serving the new bathroom light only. Am I on the right track with this or can I rely on just the main 100A / 30mA RCD? Having did a stint as a spark’s mate (back in the 1960’s) I’m OK with running it in and connecting but want to be sure of complying with the regs which are in force. Thanks in advance.
