Question:

The service entrance conductors were run in square duct located under the service equipment. A Since a water heater is at the end of the square duct, is it OK to run just that circuit to feed the water heater, in the square duct (the water heater circuit is to be fused). B Since a water heater is at the end of the square duct, is it OK to run just that circuit to feed the water heater, in the square duct (the water heater circuit is to be fused with a current limiting fuse and is part of the electric utility's controlled water heater program). C You can't run water heater conductors but you are going to run load management wires in the square duct. This is OK since the load management conductors will be fused. D The code says 'Conductors other than service conductors shall not be installed in the same service raceway or service cable', this means that A, B, and C are wrong.
A

Answer:

I hope you answered C.
