1. A TV once turned off

2. At another time, our kitchen oven, where me and my son placed some
cookies to bake, went crazy and went into a cleaning mode and burned
the cookies.

I suspect that it is so because the main 10 HP motor takes a
comparatively long time (1-2 seconds) to spin up, and draws about 120
amps during this time.

I am considering adding some capacitance to increase its starting
speed, but would like to double check if this is a step in the right
direction. I would turn these caps off after the motor comes up to
speed.

This is one of the reasons I am so PRO about VFDs. They allow you to
soft-start the machine motor, they don't draw huge reactive or startup
currents, and you get variable speed and machine motor braking, too.
Nobody in the house knows when my machines are running, because there
is no electrical disturbance.

Not exactly, All three of my VFD's will wipe out AM radio reception on a
line powered radio. Battery powered radios are OK until I get within about
6' of the VFD before the noise gets too bad.

Whatsamatta, Iggy? All those crimped connections in your RPC heating up?
Why not go on ebay and buy a proper VFD, for say, maybe $5 ? Then you can
post about it ad nauseum as you did about the now failed RPC. Give us a
break, already!

****s sake, Robert. You don't like Iggy. Whatever. We know. Why not
just killfile him and get on with life? Here, I'll show you how it's
done.

Of course Iggy and Dave won't see this because thay have killfiled me but
following is what I don't like about Iggy's form of trolling:

He jury rigs something like a RPC or some sort of a welder. Then, presto -
he becomes instant ex

Ayup. Thats also how I find CNC shops in unmarked industrial strip
"malls". I drive around with the radio tuned to 1600 and I can find
the OmniTurn lathes pretty easy.

The aim of untold millions is to be free to do exactly as they choose
and for someone else to pay when things go wrong.

In the past few decades, a peculiar and distinctive psychology
has emerged in England. Gone are the civility, sturdy independence,
and admirable stoicism that carried the English through the war years
.. It has been replaced by a constant whine of excuses, complaints,
and special pleading. The collapse of the British character has been
as swift and complete as the collapse of British power.
