RCD and 0.75kw motor?
RCD and 0.75kw motor?
(OP)
Hi all
I am using a single phase TEC 0.75kw motor on 240v 50Hz UK supply.
every time we drop the supply to the motor the 30mA RCD trips?
I know motors can be electrically noisey, but is there a simpler way around this apart from upping the RCD to say 100mA??
Does anyone know where TEC motor are made? URL?
thanks
Dave

We supply TEC motors...mainly the three phase though, because they are a CHINESE made motor, and we find that the chinese have not yet perfected the manufacture of capacitors, and have a rather heavy failure rate!
As for the RCD tripping.....have you carried out an earth test on the motor, and if so, what readings are you getting?

Jeff,
I did carry out IR test, 800 meg ohm.
Do you have URL for TEC?
thanks

Which surprised us! The connections are different in the motor terminals.
Same 0.75kw spec / chassis
