IMHO, the OP was asking how many amps of 120V load you can hang on a
200A 240V service. The correct answer is 400.

The correct answer is actually 400 amps of 120volt load IF THE LOAD IS
PERFECTLY BALANCED. * IF it's anything less than perfectly balanced,
you can not support 400amps of load. *If it's totally unbalanced, you
only get 200 amps.. *Partially ballanced, you get between 200 and
400. * *The only way you can get 400 is if it is perfectly balanced so
that the 120volt loads are in SERIES and appear as a 200 amp 240volt
load.

No, if the load is balanced there is no 120 volt loads just 240s. 240
X 20 also equal 48KW.

If what you were saying is true you could hang your ammeter on the
neutral line and measure 400 amps.

It doesnt just appear to be a 240 volt 200 amp load IT IS. The two
loads are in series, same electrons going through both of them. Its
not fair to count electrons twice.

I'm not counting electrons twice. * Neither is Bud. * I take 200 amps
worth of 120Volt eqpt and plug it into outlets that are driven off of
one hot leg of the 240Volt 200 amp service. * * I take 200 amps worth
of 120volt eqpt and plug it into outlets that are driven off the
second hot leg. * * I am now supporting 400 amps of 120volt loads.
It doesn't get any more basic than that. * I agree the current is
flowing in series and is actually a 240Volt total load and the service
is running 200 amps. *That is what I have been saying all along when
others were saying that you have conductors in parallel, a second
conductor carrying more current, etc. * But from any reasonable
perspective, if I can plug 400 amps worth of 120volt eqpt into the
house, then I am in fact driving those loads.

If the homeowner asked you how many amps worth of 120Volt eqpt is the
max that the 200 amp service can support, what would your answer be?- Hide quoted text -


By the way, are you the same Jimmie that posted this a while back?

"Assume you are using one leg at 200 amps, that is all the breaker
will handle that is 120 volts X 200 amps or 24,000 watts. If you
again max out the breaker with 200 amps flowing on both sides that is
240 volts x 200 amps or 48000 watts. Thats the same as 120 X 400
amps.
I think the OP wanted to know if he could get a total of 400 amps at
120VAC. Lets rephrase that to could he power 400 1 amp 120 VAC loads
from this box under residential conditions. The answer is yes "


So, now how come when I say the max 120v load that a 200 amp service
can supply is 400 amps and then if and only if the load is perfectly
balanced, you say NO?

If the homeowner asked you how many amps worth of 120Volt eqpt is the
max that the 200 amp service can support, what would your answer be?-
