Hi, I'm doing some wiring in preparation for my new boiler which will be going in the loft directly above the airing cupboard. I need to have an 3A DP isolator in the airing cupboard for the boiler, and I also need a 3A DP isolator for the solar water heating control panel. If possible, I would like to power both these outlets from one spur off the upstairs ringmain, although I am unclear as to the exact way of doing this in terms of the number of fused outlets and isolators required.
From reading the regulations, I am allowed to power as many outlets as I want from a spur, providing they are all (as a group) protected by an appropriate fuse. Does this mean I have have to have 3 fuses in the chain, one between the spur and the first outlet (the boiler), then one for the boiler FCU, then one for the solar heating FCU?
This seems a bit OTT so could someone please tell me the correct way of wiring up this arrangement.
Thanks
Luke
