Calculate 3 phase amperage

[brian.507679]

How do you calculate your amps for a 3 phase motor starter

 

[telectrix]

look on the rating plate.

 

[Marvo]

IL = P/ (1.732 x VL x pf x effiency) (assuming delta wiring). Or as Tell suggests look at the info plate on the motor.

look on the rating plate

I think he's after knowing what the line currents will be rather than motor current... lol!!

OP posted another thread same thing - this wants deleting!

That explains where my answer went

Those times in life when you think your losing your marbles when you find they are still sitting in your hand lol....

Thanks guys I appreciate it

I’m glad you appreciate it, most of us haven’t a clue what you’re talking about.

I’ve got serious doubts you are an electrician given some of your posts.

Agreed, I cannot work out if he wants to know how to work out the rating of the starter, the motor overloads, starting currents or running currents, sounds like another chancer, no info and the OP was so short it was bearly worth posting.
