I have a blower (metal housing) that works fine except the 2 wire power cord has been damaged. I'd like to replace the old power cord with a new grounded power cord. The blower motor is currently grounded to the metal housing of the blower. Can I just connect the ground wire on the new power cord to the ground wire that is currently connected to the motor and metal housing? I will be touching the metal housing while the blower is being used.
