Default Installing circuits in the basement.

On 11/8/2009 10:31 PM terry spake thus:

OP is treating a straightforward job in a complicated manner!

Any 'capacitance loss' is hokey. Also by the way the two hot wires in
a standard domestic North American 3 wire sytem are not actually 'out
of phase'! The two wires are the opposite ends of a single phase 230
volt secondary winding of the distribution transformer. That winding
is centre-tapped to provide the neutral.


You're correct about the capacitance issue, but dead wrong about the
phase thing.

North American domestic power does consist of two opposite ends of a
center (notice spelling) tapped transformer; the two legs are 180° out
of phase, which is about as close to "oppposite" as is possible to get.
