My understanding is that code now requires a GFCI on hardwired
residential pool pumps? I'm going to be doing some modification work
on an existing circuit, essentially adding an additional electronic
pump controller that would work in conjunction with the existing
mechanical timer. It will be inspected and AFAIK, this means I need
to replace the existing breaker with a GFCI, correct? Pumps in
question are two 1hp 240V pumps.

Correct, it use to be that GFCI protection was only required with cord
and
plug connections. Nec 680.22B, now requires GFCI protection regardless
of
connection method

Thanks much RBM for the quick answer. I guess that's another $100
out the window.

That beats my pool, which needs around 30K. With three kids soon heading
for
college, I decided to fill in the blood sucking beast . Dirt is still
relatively cheap.

Yeah, I hear you. It's actually a friends pool at his house. I'm
just a technical advisor. But before he bought the house, I told him
the pool can be a big pain in the ass. It could be worse though. I
had a boat and that's even worse.

What he's putting in is quite interesting. It's a pool heater that
uses the heat from the attic to warm the pool. Essentially it's a big
heat exchanger with a fan that the pool water runs through. With a
30F deg temp difference between attic and pool water, it's rated at
60,000 BTUs. It uses the existing pool pump. I was skeptical at
first, but the company has been selling them for 20 years and I could
only find people online that had good things to say about it.

That actually sounds like a great idea. I use to use roof mounted solar
panels. Six panels, maybe 2 foot x 10 foot. The pool filter pump sent the
water up and through them, then back into the pool. Damn things leaked like
sieves, and pretty much worked only on the sunniest days. Your friends
system sounds a bit more sophisticated, and well worth it if it gets
anywhere near 60K BTUs, especially considering the price of propane. Good
luck with it, Roy
