Note, also, that this has *no* safety circuit to disconnect the
idler when the power fails, so when it comes back on, the motor will sit
there humming until it burns up, or trips the breaker. So *always* turn
it off when you walk away.

Well nobody would be dumb enough to leave the darn thing on all
night.

Ahem.

Trouble is, this converter is really really quiet. I simply
cannot hear it running inside the little root celler it sits
in. The rubber stoppers do a great job of vibration isolation,
and I think it's a pretty high quality motor to start with.

I've got it powered off of a 15 amp breaker, through number
12 wire. The fuses in the knife switch are 10 amp, so it's on
a pretty short leash. I've had momentary lapses of grey matter
on occasion and threw the knife switch *before* spinning the
idler up - and the result is that it grunts for about a second
before one of the fuses pops.

Still a drop-out contactor is now on my list-O-stuff to do.

Until then I'll just be sure to turn the damn thing off before
leaving the shop, religiously. Maybe a note on the cellar door,
or a big red light in parallel with the drive.

Ahem.

Jim
