    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...

    wierd rfc problem

    While doing a EICR with another electrician today, we come across something quite strange on both of the rings firstly within the consumer unit for both rings there were two lines & two neutrals for each ring as there should be but only one cpc per ring, we tried to pull the cables through from...

    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?

    Testing of an RFC linked to a UPS

    Hi all, bit of advice please - as the title, I have been asked to test a RFC which is served by a UPS. It's in an alarm receiving center. Any advice on what I need to watch out for, testing protocols etc? Not workred on this kind of set up before. Regards.

    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?

    So... I've changed a CU, tested all circuits, 2 x RFC's, first test out fine, second performing end to end continuity I get 0.48 on r1, then on rn I get 4.53??? I spent best part of the day taking off every accessible visible socket and FCU on the ring, checking and tightening connections, and...

    Lighting RFC!?!?

    Evening chaps, Did a PIR other day, and the lighting has been wired as a ring and not 2 radials. Now, i could hunt around and try and split it, but i was wondering what your thoughts were on this. Its been like it for a fair few years on a 6A MCB and the owner has never had a problem...
