Hi guys
Looking for a few opinions here. I've been asked to put a small ring in just for a PC, printer, small amp in 2 rooms (4 sockets total) and 2 fused spurs off for sockets in the ceiling for projectors.
As they needed them up and running straight away another guy has put in a temporary installation until I get in there in a couple of weeks time. There are a few bits I'm unsure of so thought I'd tell you what he's done and see what you think
He's wired a rewirable RCD plug, plugged into an existing socket on the ring, running to two sockets then through the fused spur on to the socket in the ceiling, so has essentially installed a radial run of 3 sockets from the current ring, with an RCD in between. Sockets installed to dado trunking.
There are two ways of looking at this - on the one hand it's sort of like a glorified extension box with the added bonus of an RCD. On the other hand it's a permenant installation (as the dado is fixed) and it's breaking many rules as far as I can see (not tested, running a radial run from one section of the ring). It's also all been wired using 1.5mm flex. Obviously the first run from the wired RCD unit has to be flex but I would have thought if anything it should be 2.5mm from that then 2.5mm twin and earth from there on, or maybe 2.5mm flex throughout. He's changed the fuse in the RCD unit to take it down to 20amp too.
Anyway, I can see there's a chance they'll consider leaving it all as it is instead of having me put a proper ring in from the board so I wanted to see what everyone's reactions would be if they turned up to find a job like this?
I need to give them recomendations next week but as it is I'm not happy to test and certificate the installation for them becuse of the 1.5 cable and the RCD plug issue. It's an odd one!
