600v 3 phase machine in the UK

James Mardell

Hello 

I have been asked by a client to install a milling machine in a mill that has come from Canada and operates at 600v 3 phase. The machine comes with a 400v to 600v transformer. 

Are there any main considerations to take into account if this was to be installed? 

thank you.

    Check on the power frequency - if Canada is like the US it's likely to expect 60Hz rather than our 50Hz - which might have have a knock on effect on a number of things, not least the speed of 3-phase motors.

    Also the transformer may well have a large start-up current - often D-type MCBs or over-rated fuses would be called for - with implications for Zs and so circuit length/c.s.a. etc..
