I realize that it is good practice to use a "NO-OX" type grease when connecting an aluminum cable to the main lugs of a residential panel main breaker, but does the NEC spell that out anywhere?
Re: NEC Requirement for "NO-OX" Type Grease
110.14 discusses it a bit.
Re: NEC Requirement for "NO-OX" Type Grease
The use of oxide inhibitors is not required by the NEC.
Unless the directions for the equipment you are terminating to tell you to use it.
Then it would be required by 110.3(B) and would have to meet the requirements in 110.14
I recently used a GE safety switch that stated to wire brush the conductor and use oxide inhibitors if using aluminum conductors.

Some oxide inhibitors say not to wirebrush the conductor. :roll: Read the directions .
Re: NEC Requirement for "NO-OX" Type Grease
And some say to put the stuff on before you wire brush.
