@bearlovesox The 500 has to lug a heavy-ass siren round on its rotator, I doubt it's single phase otherwise it would be even slower wind-up.

You know what, this tells me that the Federal 500 here in Reedsburg is single phase. I have wondered why it sounded so different than a normal STH-10 and this must be the reason, they sound exactly alike.

whats the difference between a sth-10A and sth-10B?
hootergirlsrhot 1 year ago
STH-10A is three phase, STH-10B is single phase.
Externally, the STH-10B uses a larger looking motor with a ridged top.
