Some times I see other electrical devices being feed off the motor/overload terminals of a motor starter. NEC article 430 only addresses overload usage with motors.
I have not come across any manufacture specifications that says it is permissible to size overloads with other electrical devices or controls. It has always been my understanding overload protection on a starter is for individual motor protection.
Are some doing this because the informational materials don’t actually say nothing else can be connected to the overloads with the motor? Also what is UL and OSHA impact on this?
