I recently looked at a job where a customer is turning his garage into a workshop and he wanted me to check the electric was satisfactary. The garage is fed by a 2 core 4mm SWA from the house with an earth pin outside the garage and a 4mm earth going to an rcd board. When the customer showed me what he would be doing I was shocked, he has bought lathes and CNC machines from a warehouse. The machines are all 3 phase and he only has a single phase supply. He seems to think you can buy a converter which you plug in and it converts single phase to three phase????? has anyone come across this before?
Secondly the machines are 7.5 horse power would a 4mm be capable of this load? Im tempted to put in a 6mm as he says the converter needs 30-40 amps to work?
Any ideas???? Also do lathes draw a high start up current?
Thanks guys.
