32A Supply in Shed for Welder and Plasma Cutter

Postby paulcornwall » Fri Jul 27, 2018 9:26 pm

Currently, have a 13a supply to the shed/workshop. With my recent purchase being a welder and air compressor I'm now needing a 32amp supply to run a plasma cutter.
I currently have 6mm SWA running from a plug socket to a consumer unit in the shed.
I know I need to rewire to the house consumer unit but do I need to place 32a RCD's in at either end (at the house cu and shed cu?)

I am aware this type of work is notifiable etc etc.

Simply Build It

There is no point in doubling up, however the main problem is supply. If the equipment causes dips in the supply then you can be told not to use the equipment.

You need permission from the DNO.

In real terms some one needs to complain.

You really need to get this checked by an electrician, it's NOT a diy job.
