Hypertherm plasma cutter advice.

[T0rnado69]

If this is in a domestic environment you might have to upgrade the consumer unit as well. I think the incoming fuse is rated at 100A but they used to be only 60A. I don't think the electric board would be happy either.

CU was done a while back, and i upgraded just a simply ring main into garage to a sub main.
as i was tripping the house's RCD sometimes when putting the lathe on.
guess kids had tv's and consoles on, maybe with washing machine etc.

so changed from having just a ring main to having a sub main CU in garage, supplied from house's CU on non RCD side on a 63amp MCB
but i dont know what the main fuse is... think it might be an 80amp

Your best idea would be to get a professional electrician to look at it. The cable sizing depends on the installation method, load and length of run.
so your consumer unit and main fuse should be able to handle it ok but you may want to be careful on what else you are using at the same time as running the plasma at full current.
Yes the plugs and sockets do start to get expensive at that rating.

my mate is an electrician, so no problems there..length of run is only about 20ft.
currently have it in 6mm T&E with 240v 32amp socket.
yes the CU is fine and i can upgrade the MCB to higher rating if required.
i only use one thing at a time. except what the kids have on upstairs if they are in.

Not too expensive if you don't need waterproof RCD units -

Definitely worth checking what overall current draw your household would have if you went out & fired up the plasma and the compressor kicked in whilst someone indoors put the kettle on and had a quick shower whilst the immersion heater warmed up the water for a proper soak ;-)

cheers for the links nick...
yes something too look into, the compressor cant come on, unless i have switched the neon spur switch for the comp...
kids dont use kettle for hot drink. as they drink squash or fresh orange..
shower yes thats possible, no immersion heater, combi boiler now..
but i get what your saying :)
