Where I work we usually test circuit breakers 400A and above but I have done panelboard branch circuit breakers before when it's called for in the spec (typically government and data center applications).Originally Posted by changeabilities

This is for acceptance testing by the way, I've also seen specs that call for "main breakers" only. For maintenance we usually secondary inject unless the customer requests primary, same 400A and above rule usually applies if customer has no idea what they want to test. Which application is this?
NETA ATS and MTS both state that the owner/user is responsible for deciding which equipment to test.
ATS 4.1.4
MTS 4.1.3

A lot of times it's up to the customer and what they want done.

As said above NETA states it's up to the customer, but speaking from experience anything above 400A is generally tested, below that is very rarely tested.
