Re: Installing A Thermal Overload
IF you think about it, it doesn't matter. IT's a complete circuit regardless. But I've always seen overload after the contacts on a contractor. In this case, there's just a on/of switch not contacts.
For some clarification. A breaker protects the wire, primarily in the branch circuit against peak currents. A overload, is a device that protects the motor against sustained high currents to protect the motor insulation from thermal failure.
Large motors with straight line starters usually have a contractor (which is just a big relay) along with a manually or remotely resetable circuit breaker and thermal overloads.
