I ordered a hard-to-find 200A main breaker to upgrade an old Murray panel to its full rating. But when it arrived, it was only 10kAIC, vice the 22kAIC breaker I wanted.
The Pole Pig (240V 1-phase secondary) is 25kVA- at 100% load, that's only 104A, yet this pole pig is feeding two homes with 200A services, is that normal? I know they can operated overloaded, but to actually install one like that?
But my big question is, what's the fault current for a 25kVA pole pig? I'd think the core would saturate LONG before it gets close to 10kA, but I want to make sure.
