Mr. jim18655 has all the right answers.
You have two choices. Only wire one speed of the motor with the proper size heaters installed or get a two speed magnetic starter and install all six heaters of the correct size. Why six? Three for each speed same as your single speed contactor needs three for one speed. Why? Code requirement for proper safe operation. If your starter only has two overloads it is out of date and non code compliant. One heater is required for each current carrying leg of a 3 phase motor circuit. Sorry, have to keep up with the times. Anything else is bad info.
Great information!!
Thank you all.
Code, OSHA, and other regulations aren't usually in place just to be a pain...
There are real and appropriate reasons.
We all make choices. We live and die by those choices. Yes, sometimes we die by the choices we make.
If I understand your post above. Then I need to rewire all the old iron I have.
Hmmmm...
Thank you for all of your responses, I got some shopping to do.
And I'm not sure that merely loading W50 is the best answer.
