Thread: Higher current single phase 240V?

That's a lot of power, what are you planning to run? You would need to run a bigger cable back to the main switchboard and instal a larger circuit breaker at the main board for it.

Not sure what power you already have - does it run out of a sub board in the garage? If not, you will need to put one in there to break the 32 amp supply down to the final sub circuits or power and lighting that you need.

If your current cable (bad pun I know) is quite small and it is run underground in a conduit, then the bigger cable may not fit in the existing conduit and you may have to dig a new trench and start again...

Would be easier if I had a look - I'm up your way a fair bit or work. Happy to drop in one day and assess what you have and what you may require.

Cheers - Gav

It depends on what cable has been run, does it have a sub board? If it has 6mm cable feed from main switchboard you can get your 32A, if it's just tacked on a power circuit from the house 20A is it, you'll need to run new sub mains from main switchboard

Why for?

32A is a large supply. I think a typical house supply nowdays is 40A or 50A.
Give an electrician (or Gav) a call.
This could assist where to go next.

I had a switched Clipsal 56C332 (i think) 250v 32a 3 round pin socket fitted in my garage, on its own circuit breaker, by an electrician. (handily main fuse board was on outside wall of garage)

The socket was ludicrously expensive from memory. I think the socket, plug to suit for the welder (as the 32amp plug it came with had a different pin configuration), circuit breaker, and wiring, and about 90 minutes work was over $700.

He did do a good job though.

I think the plug I used was a 56P332.

There are a few on ebay at the moment so it may well be worth looking at those aswell.

Should make the cost back once the crop is sold Or it`s going to be a decent man shed being set up.

How far from the main switchboard to the shed, you'll be surprised how short a distance a cable can be run before volt drop takes affect.

it is to cater for a cnc plasma cutter table, and a small biodiesel processor down the track

the main board is in the hallway at the front of the house, and the sub-board in the garage is 20-25m from that

MMM plasma cutter table sounds very cool toy, so soon you can pump us out metal "red rat" stencils in metal ??

(if so prepare for a heap of REMLR typr mates to start popping up from nowhere............ mate !! )
