    Computer RFC Testing???

    I'm scratching my on this because I've never done it before. I'm on a new build school wire with quite a few computer RFC's using 2.5 T&E + a 4mm single Earth that we are just pulling in now. When it comes to us testing these circuits, how do I/we record the results? Both the 1.5mm CPC and the...

    RFC using conduit as cpc

    What is the best way to confirm r2 and R1+R2 when the circuit is routed in conduit and this is used as the cpc? I have used wander lead and got continuity at all points on the circuit for the cpc. rn and r1 are within 0.03 of each other so no problem there. just how to confirm that the...

    Coax and RFC spur

    Went to replace a corroded socket outlet today and found that the TV coax is crammed in the same conduit as the 2.5mm spur feed cable, then passes out of the mains backbox into its own aerial point box. No way to re-route it without major upheaval for a very nice old Lady. Thoughts please.

    Why are you only allowed one spur per socket on a RFC?

    This is something I have been racking my brain over for ages and its doing my head in!! :crazy: Please could someone explain why you are only allowed to have one unfused spur per socket on a RFC? I'll explain a little why I'm confused. A ring main is allowed as many sockets as you like on the...

    RFC - end to end on CPC higher than expected ( EICR code advice please )

    In the process of a domestic EICR. RFC, i'm getting L-L (0.11) N-N (0.11) cpc-cpc (0.48) had to take off all socket fronts anyway as i did not like what i saw on a couple of random selected s/o & i've tightend up any loose cpc terminals i can find. I'm guessing that there could be a JB with a...

    kitchen 32a rfc or 2x a3 radial

    Just thinking about a kitchen circuit, How close would i be pushing a 32a rfc with washing machine, dishwasher, and two double sockets (likely to use kettle and toaster at the same time ) would 2x A3 circuits be more sensible?

    RFC - no CPC continuity!

    Hi, I have just tested a RFC and the CPC was broken (no continuity). Tested all the socket on that circuits and R1+R2 was OK but I could't open a socket to check, as it was hidden (burried) behind a door frame and it must be a double socket with only one of its switches staring at me. To reach...

    Dead short between line and neutral- RFC

    I am getting a dead short between line and neutral on an IR test on a RFC. The second RFC is giving 0.30 M Ohms!! I have removed all loads as far as I can see including a TV amp in the loft (although there is no seperate power feed to it). I have split the ring but its not easy to work out...

    continuity test on rfc

    hi all i'm doing a continuity test on rfc r1=.70 rn=.69 r2=1.14 but when doing r1+rn/4 it should be .36 but getting .74 on all sockets and r1+r2/4 should be .46 but getting .83 on sockets is this just due to loose connections somewhere thanks in advance

    High rn on RFC, what to do?

I spent best part of the day taking off every accessible visible socket and FCU on the ring, checking and tightening connections, and...
