Good point Jay. I'm sure we all strive for uniformity and a one size
fits all solution, but I agree, in the end every site is unique and
requires custom solutions tailored to its actual conditions.
Always appreciate your thoughtful take on things,

One issue that has been troubling me is the 1 size fits all.
We live and work in many really different environments.
Because of this, what works here might not work there, but just
because it doesn't work there, does not mean
that I shouldn't be able to use it here.

Darryl, see my post yesterday (I think). If you have the tonnage and the
SEER/EER you know the operating current, period.
As for start up transient, I think we need to get help from someone who has
actually measured the transient (I think I saw a post about that a couple of
days ago?). And, when
I use for a short cut 1 AC ton is 1 HP mechanical or 1kW electrical.
So If I have a 3 ton heat pump I figure the compressor is about a 1 horse power
motor and about 1 kW running load. If that is 240 volts that is about 4 0r 5
amps. Because I have had some starting problems, I say that the runni

We don't use braided for direct burial. We use it to bond to the
array, run with the PV wires, and switch to regular copper as soon as
we go into conduit at the first J box. We zip tie it together in a

We installed fronius inverters outdoors in Durango, CO. I did not do the

operated just fine throughout a very burly winter. Hope this helps. You

I was under the impression that braided or fine strand wire was a no-no for

Hi Peter and others,
This has been super helpful.
My customer's electrical designer has calculated the AC units 2.5 ton
at 9.5Kw.
so this really helps me to be able to go to him armed with good data.
thanks again,

There are two figures of merit that can be used to make the conversion. The
simplist is EER.
First, how many "tons" the AC is rated at? Multiply that number by 12,000
BTU/hr per ton, to get the number of BTU/hr the AC system can pump out of
the house.
Second, EER is the ration of the BTU/hr to e

Hi Travis,
thanks for the great insite, this helps a lot.
So the higher the SEER number the more efficient the unit is.

I hadn't heard about condensation from infloor cooling but makes
sense that it could happen.
Most of the infloor cooling that you are mentioning is from a
regular AC unit not say using solar thermal panels at night?
