Surprised

[Pete999]

At how many new, Electricians or near qualified Trainees are unsure of how to wire RFCs in conduit, Plastic or Metal, advised a guy the other day who had taken a leg right from the last Socket outlet back th the CU through the tub bypassing all the 13Amp sockets, wanted to run another bit of tube back to the CU for the return Leg. Do the training establishment teach this simple task? just wondering. Anyone.

well Pete gods like us need to go to earth and show them .is the one day wonders cant do it .never been trained . god help them .

Seen it done in dado trunking. DB at one end of room and around 25ish meters of trunking in a U shape. DB within 2M of closest group of 4 sockets. 1st leg of RFC to closest socket which is fine but return leg was connected to the furthest socket. So about a 30M run instead of 2 or 3.

Simple in trunking Mate a no brainer in fact.

no brainer if he cant do that .

Well there seems to be plenty that can't Buzz

So let me get this straight because I'm having a brain-fart; rather than feed the return leg through the same conduit it went to the sockets in, they wanted to run it back in a separate piece of trunking?

when i used to run a rfc in dado, i'd run 1 leg through sockets 1,3,5,7..... and the other leg through sockets 2,4,6,8......

and sometimes i managed to keep the cables in the right compartment/s.

That’s what you do if you’ve got a lot of short lengths of singles

Pete, during my brief training I wasn't taught how to wire a RFC in conduit specifically, but I was taught to wire a ring reasonably balanced. In situations where there would be a very long leg from the final point back to the CU, the solution offered was as per Tel's post, or to wire a radial instead.

Don't understand Mate, are you saying that how you wire the RFC in conduit is dependant on the length of the cable you are using?

personally, I do it the way tel says... 1,3,5,6,4,2.... but others I have worked with in the past have done it 1,2,3,4,5,6, back to CU.
(just using 6 points as an example)

it’s a ring, so hypothetically, you could do 1,2,5,3,6,4... but that would just be daft.

I thought the issue with the OP, is running a separate conduit back to the board for the return legs.

Yes it is, the person I was trying to help out, couldn't understand how to wire a RFC in tube WITHOUT running the tube in a ring ie tube from CU to socket 1,2,3,4, etc and a run from the last socket back to the CU, just couldn't get to grips with how to do it the way Tel suggested 1.3.5.7.9 etc, the reason for my post, initially was to try and find out how this is taught at College these days, looks like many different people have differing views, thanks for all the input folks.

The Chinese way, is the best method on a single piece of conduit.

????? Chinese way, heard it called some names but Chinese??

 

[ipf]

One run of conduit with two lots of cable OR two runs of conduit with one lot of cable?....that really is a no brainer.
Failure to work that out may result in the Japanese way...…..Hara-kiri.

Well Pete that's what we called it in London circa 1970's

Thought it was some local name, Dave, thanks for letting me know, from now on it's "The Chinese way" in my neck of the woods. Like it, very apt.

That's what I love about the forum Pete, we all have our personal journeys, and experiences, you just cannot buy that.

Out of interest, why would you choose to wire this sort of circuit as a ring final? Surely a radial is the obvious choice for something like this. One run of conduit, one run of cable.
