RFC in Steel Conduit

[telectrix]

i'd switch them in pairs then. so only a 4 gang switch. K.I.S.S. is what my old man taught me.

How big is this garage?

I still struggle to see how the lighting and ring main will pass each other in the tube and you will have met regs regarding factors, sounds like you need a 2x2 glav trunking running around at high level and conduit drops, may be worth replanning the whole scheme to be honest, or perhaps you can explain your thoughts about how you intend to wire this so we can understand a bit more about your design.

Ok, ring is 4 x 2.5mm -> 4 x 30 = 120 cable factor
This needs to run past the supply to last two lights which is 3 x 1.5mm (N + 2 switched lines) -> 3 x 22 = 66 cable factor
That's a total cable factor of 186 (the ring does not need to run past the grid switch)

20mm conduit allows 10m for 1 bend, 5m for two bends and 2.5m for three bends.

I could just keep the two conduits running in each direction separate, they would pass / run along side each other at the far end, but given that all the cables there would fit in one conduit I thought that wouldn't be necessary.

Go on, I know I've probably set myself up for a fall now :army:

Fair enough Tuttle if you have gone to the trouble of calculating everything then it may well be fine, to answer your question, feeding the ring from one end of the conduit and then out the other is fine, or wire it as Tel mentioned, one leg to odd sockets one to even sockets and link between the last 2, that is what I normally do, either way it is fine.

 

[telectrix]

maybe not a fall, but a bit of over complication. still, a slong as it complies, it's you job at the end of the day, so do it as you think fit.

 

[Tuttle]

Thanks guys, really appreciate your responses

I bet, eventually, you'll get fed up with flipping 8 switches to turn your lights on!!!

Probably only switch one or two of them on most of the time, that's the idea anyway.

Wire it the Chinese way, Trunking around the area sounds the best way, then drop down in conduit.

Trucking?

 

[Pete999]

Keep on (trucking)

 

[telectrix]

in this?

 

[camerabloke]

Enough room in that for a RFC

 

[7029 dave]

HA HA my bloody eyes!!

Depends on the floor area, could be an earthing problem as well
