I’ve recently seen a motor wired directly from the local isolator to the motor terminal box in 3 core 1.5mm cable. The gland has been made off into a threaded hole in the motor terminal box and at the isolator end directly connected to the incoming swa from the MCC by means using a flylead. My question is is this a sufficient for earthing the motor. My understanding is you can use the armour as a cpc but wasn’t sure if any additional “fly leads” should be fitted at the motor end?
thank you guys!
