Best solution

Hi Guys looking for some advice, my friend has asked if I cant install 8 double sockets in his lock up so he and his employees can do a course there. I asked what would be plugged in he said 7 transformers im guessing 2.25kva and that would be feeding the heat guns they need. 1600W each. If all those heat guns are used at full load at same time thats about 46 amps, plus the transformers. Would I need to do a radial circuit with bigger cable or would A ring at 32 amps 2.5 cable be ok depending other factors.

I guess all heat guns wouldnt be used at the same time etc and not at max temp.

What voltage output are the transformers?

What voltage output are the transformers?

110v

i woulddo 2 x 32A radialsin 4.0mm. 5 sockets on each.thatleaves a coupleof sockets for kettle/toaster etc.

I have just found out its a single phase board thats in already. Would that change things

As Tel said

2 circuits is better than 1

I suppose capacity and voltage drop would need to be checked

Probably need C type mcbs for the trafos so that has to be factored in

Install a wall mounted 110V transformer and fit 110V sockets

Best job alright I've done that before for school workshops
