The saw is a “2HP” motor. In reality I suspect it’s probably closer to 1.75. Motor pull 16A at 110 and 8A at 220. I get that the startup draw can be significantly more, but from what I understand, isn’t that a very temporary draw that’s so short it’s not supposed to trip the breaker? Grizzly’s manual calls for this to be run on a 20A circuit regardless of it’s 110 or 220 – they also said it was okay when I talked to their tech support guys. I’ve also got a bandsaw and a dust collector with 1.5hp motors that don’t ever trip the circuit.

Who knows though. Maybe I’ll have to get my panel upgraded again, but right now I’m just going forward assuming it’s the saw. Hopefully I can get back into the shop to do more testing tonight.
