New toy.

Arbalist:
Dave doesn't specify what "other motors" he wants to run on three phase so I'm wondering at what point it would make more sense to get a three phase supply? Cost must vary a lot depending on location etc but I'd certainly beg the question before looking at converters etc. it won't cost anything for a quote.

awemawson:
When we moved here I rang EDF for a ball park figure for running three phase into my workshop overhead from the transformer that is less than 50 foot from the building. I was told a minimum of £5K and I budgeted £7K for the work and put in an application.

Within a couple of weeks some yellow coated EDF men came knocking at the door, I assumed due to my application. No, they wanted a way-leave to grant access to their transformer to replace the cables with the new 'bunched' ones.

I swapped a way-leave for my three phase connection  :lol: :lol: :lol:

When they came to re-cable they couldn't get their digger under the guy wires for the transformer poles and I ended up lending them my small one  :scratch:

Arbalist:
Nice one Andrew!  :D

awemawson:
 :thumbup: oh YES   :thumbup:

They then came back again a couple of weeks later to borrow my 100kVA generator (now sold) that they'd seen me using while they were doing the work here - they were re-wiring in a local village that had a nursing home that needed to be kept live (or at least the patients did!) - it came back with a full tank of red diesel and several bottles of Irish Whisky  (the crew were Irish)  :ddb:

DavidA:
I had considered asking about a 3 phase supply.  But as the local sub station is nearly quarter of a mile away I thought it would probably be prohibitively expensive. I am situated right at the end of a cul de sac so probably also at the end of one phase.

The other motors I would run are a small vacuum pump (fractional HP),  and a couple of drills that come with three phase motors.

It would also allow me to use small (<1.5 Kw) motors for other general purposes.

A bit of noise isn't a problem as the rotary would only be running for a few short periods at a time. And as it would mostly be running just the lathe (max 1.5 Kw) which would not be over worked,  I foresee no problem.

Only one tool at a time would be used.

I think a 2 Kw unit would probably do me.

Dave.
