i know i am more than likely explaning this right but could reduced voltz say as low as 185v on a 208v, 12000 watt system burn a four leg 40 FLA contactor

If I'm drawing this right than contacts A and D will see more of a draw than B and C, but still if this heater is rated at 58 amps the contacts should withstand the current. Back to my first question what type of coil is being used on this contactor if it is a lower voltage I would lean towards chattering being a problem.

 

[Strahan]

True for a resistive load. My question was pertaining to the motor an inductive load and if it was attatched to the same contactor.

i don't understand coil or how to tell please eleberate

 

[ROD BAKER]

no it is not connected to the same contactor

Rod, the forum is for those in the electrical trades/industry, (see the forum rules) I allowed your thread because you were not directly asking a "how to fix this yourself" type of question, now I question my decision and must suggest you hire a local EC to assist you in trouble shooting this problem.

With that said, I am closing this thread.
