How freakin stupid are you? Grab your tools and go play in the rain
and see how much fun it is. You'll also notice a bit of rust on your
tools a couple hours after you finish. Tools are expensive. I guess
you're going to pay for them?
Not open anything on your units to service them? What kind of clowns
are you hiring to work on your shit.
Im going to set you up for the dumbest post of the month.

Funny story... OT to the post but in the same genre.....

I have a customer that has a 6.5 megawatt induction furnace for melting
steel.

Two nights ago, during a furious rainstorm, a part of their roof failed
that happened to be directly above the power unit for this furnace.

The roof is less than 10 years old and developed a serious leak around a
exhaust fan. The roof drains were plugged.

Anyhow... the power unit for an induction furnace this big is
essentially a huge 'variable frequency drive'. Its capacitor bank is 16
feet long and 8 feet wide. The inverter section is another 8 feet long,
has 24 platter size SCR's in it, and various control components.

I got a call-out that the Inverter buss was alarming on the - (minus)
side. That's all they told me. When I get there.... a steady stream of
water is cascading from the roof onto the power unit... directly above
the inverter section. No-one had turned the power off. The operator told
me he tried to 'reset' the unit multiple times but "it just went BOOM
BOOM BOOM... like a shot gun".

I immediately opened the breakers, L/O'd the unit and told them to fix
the roof before I could do anything. They had to 'dump' the furnace and
get rid of 20 tons of steel at 2520 degrees. That was a spectacle in itself.

The first call was around midnight. It was 6 in the morning before the
roof was fixed, the water stopped falling, the furnace 'dumped' and we
had dried things out a bit.

Our crew of 7 worked 18 hours on this project. Every SCR assembly had to
be dismantled and dried. 11 SCR's at $1,200 a piece had to be replaced.
Two tank capacitors.. big fellas... water-cooled jobs.. were blown to
bits... $6k there.

The entire bill was $87,260. Because no-one turned the power off when
electrical components are exposed to water.

Water and electricity don't mix. To the OP, be glad your contractor
wouldn't come out. They were protecting you and your equipment.

I'm remembering a job I had a couple years ago. The upper middle
class lady noticed the AC wasn't blowing. She came downstairs and
found the breaker for the furnace off. Single pole, 15 amp. She
reset it, repeatedly, until the breaker stayed on.

What happened was the fan blower motor shorted. Five year old
furnace, a Bryant. Every time she turned the breaker back on, it
shorted through the motor. Finally a couple relays on the circuit
board vaporized, and that needed to be replaced, also.

I don't remember the numbers, but the parts really added up. Plus
the house call and three hours of labor.

I think they get an atta-boy for calling you to let you know the
appointment was being cancelled.
