Shunt Trip Factory Pigtail Wiring supplemental Overcurrent Protection?

[STUDENT OF THE TRADE]

I have an inspector requesting additional overcurrent protection for the #16awg wiring connected to #12awg wire protected by a 20amp single pole breaker. What is the code section to reference voiding his request?

Help me understand the situation. What type of equipment are we talking about? Where does the pigtail come into the story? For instance, is the #16 wire provided by the manufacturer of a light fixture, and are you connecting it to a 20 amp branch circuit feeding the lighting system?

Generally (with some exceptions) you protect the wire at its ampacity.
Does the shunt trip breaker manufacturer have any instructions associated with it that may instruct supplementary protection.

The inspector should tell you what Article is violated. This would be no different than requiring supplemental OCP for a door bell transformer. Have never seen that requirement either.

Thats a good point. Why hasn't that requirement been enforced. Maybe because of nonincidents. A simple in line fuse holder would satisfy article 450 but i wouldn't want to be responsable for putting an inline fuse on a shunt trip breaker and having it fail when called apon.

There are 100's of devices made with smaller gauge wire that connect to

larger branch circuit conductors, I think he is mistaken.

dimmer switches
solinoids
motion sensors
bath fans
door bell trans.
ballasts
etc.

I'd pose the question differently: what backs it up? The burden is on him.

This isn't branch-circuit wiring, it's equipment. What does the manufacturer say?
