Model 5T 120V and 240V Tests

[Adam Pollak]

These were made about 4 and a half years ago of my Model 5T running on 120 volts and 240 volts.

Nice, Adam! Man you have too many rare sirens.

How do you keep it from spinning around? When I powered up my model 5 motors alone they jumped. I figured with a rotor they would move all over the place. In the 120 volt video the thing doesn't even budge and that's with it having to get that rotor going.
In the second video it looks like you have it attached to the plywood. I guess I need to get one of my Model 5s put together and buzz it. What is the current capacity of the breaker you are running it through?

We have our model 5 ran through a 30 amp 240 breaker. I probably would go for something higher like a 40 if it was going into service but the 30 holds ours fine for the new years full run and the growl test every once and a while.

There's enough friction on its own to keep the Model 5 steady on the 110. If I did not have it on the wood for the 220 volt test, it for sure would have gone spinning around. The only redeeming quality to that is that the rotational inertia should hopefully be enough to keep it from tilting over.

In that video, I cannot remember which way I had it wired, as I've run it 2 ways and I don't remember which way it was. The first way was wiring it into the 30 amp dryer outlet and switching it on with the breaker (which I think it probably was for this). The other way was from the RCM1 panel that I wired in with its own subpanel. I would just wire the Model 5 into the blower's motor starter and use the test switched to turn it on and off.

I've never tripped that 30 amp breaker when I've played around with it before except one time when I was running the thunderbolt. There was a tarp resting over it to keep it dry and I was dumb enough to run it with that on. The blower lost some of its airflow and that increased load was enough to trip the breaker.

I buzzed the Mod 5 motors with my 30 amp hookup I put it for testing choppers and rotators. When I get one put together I'll use that again.
Thanks for the info Adam.

Adam, did you use a 30A breaker on the 110V test or was it standard 15/20A breakers on that one?

[Adam Pollak]

That was just a regular 20 amp breaker I wired it into. I have no idea what the current draw was, but using the visual arc-when-unplugging-scale I'd say it wasn't that bad...whatever that means. That's also my memory from 5 years ago though. I've never tripped a 15 or 20 amp 115 volt breaker with a siren though.

How many amps is your 5T supposed to pull?

I'm curious because if you ran your 5T on a 120V 20A circuit, then maybe I could get some noise from my STH10 on a 20A circuit.

Siren spec table, click me

the 5B(T) is 56A 240v. 100A time delay fuse and 2 AWG wire recommended.
