Bruce,
Probably should kill this topic for it has radiacally changed from orginal
posting and not really repeater related although AC power is a concern for
about any repeater builder.
I think one reason for separate wiring to each outlet is the way so many are
wired using the little spring loaded connections that require only stripping
the wire and inserting...do not use the screw terminals that most all have.
Over time the spring tention weakens producing a poor connection at one outlet
that can lead to a high resistance and heat. Having multiple outlets on one
string of wiring can amplify this situation.
I don't like the strip and insert connections and think they sould no be
allowed. Whenever I replace/repair an outlet I cut the wire and connect to the
screws.
I am sure there are other reasons for separate wiring to each outlet. The
electric code has many not so obvious reasons for what they do mainly from
experience.
