7.5kw motor

[shurbunkin]

hey guys



ive wired in a 3 phase motor for a work shop and i think ive connected the phases right. It doesnt need a nuteral and the earth is bolted to the metal work. ive switched it on but when it starts the motor runs for about a second then stops and the breaker trips. Its got a 16amp thre phase breaker supplying it. I think it needs a 20amp. Just wanted to make sure incase i damage the equiptment.

The connections ive made are l1 to w2, l2 to u2 and l3 to v2 of the motor and have metal links between w2 and u1, u2 nd v1 and v2 to w1


cheers guys

It's Delta I think, by the way his links are.

its for a power unit driving hydralic pumps. The motor rating is correct. Im wondering wether i need to put i higher breaker in

 

[shurbunkin]

taking the board cover off the cable size between the board and the comando socket is 2.5mm which seems way to small

Oh for god sake get an electrician in will you!

"I think I've done it right???"

Do you now?! Well my friend, if you were competent to be carrying out the work in the first place you'd know if you'd done it right!

FFS! I feel like crying sometimes!

Why do you think the 2.5 is to small?
We really need to see a rating plate.
