    Calculating Cable Size for Ring Circuit

    yeah my main incomer is 400A Switchboard, i've then got a 3ph DB in each stand. It's just sockets just now with the view to maybe sticking a guy with a hot dog roller machine in the corner for the bigger matches. it wouldnt ever be on the scale of a burger van rocking up and plugging in. I've...

    Calculating Cable Size for Ring Circuit

    Okidokie, thanks for the help. I was planning on using a 6x6 JB and coming out of there into the socket so I'm along the same lines of thinking as you. Many Thanks

    Calculating Cable Size for Ring Circuit

    Pretty much, but at least they know they wont get more than 32A from the circuit. i think the idea is much like a cleaners circuit, you know that only 1 or 2 will actually be in use at a time.

    Calculating Cable Size for Ring Circuit

    Its like 25mm or something daft, 6mm is ok for sockets, 25mm is pushing it o_O

    Calculating Cable Size for Ring Circuit

    I did say i didn't think i'd explained it very well Pete. the problem is that yes i will have 8 RFC doing 40 total sockets, I still have the issue that an RFC is still going to be 300m on the longest. I'm more than capable of doing the work i was only looking for a nudge in the direction of how...

    Calculating Cable Size for Ring Circuit

    To be honest at best i think they're thinking more hotdog warmer etc than full setup, otherwise in that case i'd run a 63A supply to an isolator. The unfortunate part of this job is that its design and build so they wont commit themselves to a spec. At the end of the day if they try and pull...

    Calculating Cable Size for Ring Circuit

    I have but I cant fit small CU's all over the stand, and if i tried to do it in one run its 150m so therefore a 25mm SWA is needed, which obviously inst viable for a few sockets. Maybe didn't explain it better before but in one stand they are asking for 40 sockets, 8 circuits, 5 sockets each...

    Calculating Cable Size for Ring Circuit

    I went for a ring rather than a radial as then I can allow the higher volt drop without having to up the cable size too much. It may be a surprise but i am a sparky, i'm fine and happy doing cable calcs on radials but was looking for a bit of help on the ring side of things. The sockets are...

    Calculating Cable Size for Ring Circuit

    Thanks for the replies. It needs to be in SWA as it's for a new football stadium. I can run a small DB closer to the location but each run will still be 150 there and back so i'd still need to run the calcs. The plan to terminate the armour would be to mount the socket on a 6x6 joint box which...

    Calculating Cable Size for Ring Circuit

    Hi All, I'm needing to calculate the cable size for a long ring main. Cable type will be SWA/LSF. The ring is feeding 5no Twin Sockets, on a 32A Type B RCBO, kicker is the length out and back is 300m. Using cable calculation tools can i half the length, 150m, half the current, 16A and allow 20%...

    Rotary Isolator that takes 2x16mm?

    Fortunately its not on my head, been designed by a consultant being an airport. The runs are about 150m each so its more for volt drop than anything. Basically going to be an isolator on the outside of the pillar, going through the back to a spur which will then feed the gubbins inside.

    Rotary Isolator that takes 2x16mm?

    Circuits only a 20 amp supply, the rotary isolator will feed a fused spur, no lights, just power for barriers.

    Rotary Isolator that takes 2x16mm?

    Thank Tel, thought i'd have to go main switch, mainly for the working space inside.

    Rotary Isolator that takes 2x16mm?

    Does anyone know of a rotary islotaor, weatherproof, that'll take 2 x 16mm incomers? I've got long runs out to parking bollards so they've had to size up the cable for volt drop. I could do it with a street light cutout but it wouldn't allow them easily isolate it. Many thanks for any help.

    Suspensions for track lighting

    thanks, that'll do the trick if i can't find the original, the problem is the guy ordered 30m of track and got suspensions to fit, but he's miscounted and i've had to get another 10m of track and need the suspensions to match, i'm sure i can make it work though if i need to. Cheers

    Suspensions for track lighting

    Hey guys, I'm looking for some suspension kits, i have a photo of what we currently have but need another 10, the guy who got them has left the company and i cant get hold of him to find where he got them. Our usual wholesaler doesn't recognize the part at all. Does any one have anything...

    let down by 'top brands'

    Looks like a less convenient way than just using a bit of plastic trunking lid, fish through trunking, basket, fish round corners too.
