Question: I have a 125A breaker frame (came without the hardware) to bolt on to the fingers in a 480V 1000A dist pnl. Looks like 10/32 but that doesn't feel right when you try to bolt it in. Anyone know for sure?Thanks
The correct bolt size for a 125A breaker frame in a 480V 1000A distribution panel is 1/4-20 x 1.
Note: While 10/32 bolts may seem to fit loosely, 1/4-20 bolts are the industry standard and provide the proper clamping force for electrical connections. It is crucial to use the correct bolt size to ensure proper electrical contact, reduce the risk of overheating, and maintain the safety of the electrical system. Flag for review
