When I do something contrary to the directions I am always a bit nervous...
I wired up a double pole switch today. The directions say the load goes to
the light terminals, and the line goes to the dark. Since my line comes in
from the top and the load goes out the bottom, it was much more convenient
to wire the switch backwards. I can't see how it could possibly matter; am
I overlooking something? (No, the next guy won't be confused; the load is
an outlet 5" away.)
What size and type of douple pole switch is it? If it is a snap switch
that is comletely enclosed then there is no problem. If it is a larger
enclosed switch contained in a cabinet then there is a real danger.
Please advise which type you are asking about.
Back in the old days -- early 1900's -- when electricity was in its infancy,
there were electrical boards with open knife switches, usually 2-pole. The
switch was mounted so that to open the switch you pull the handle down and
out of the blade contacts. It was wired so that the hot line was on the top
and when the blades were pulled out the blades were no longer live, only the
top section was live. Some of these switches were huge. The snap switch
that you are considering is enclosed, so the safety factor of wiring the
live wires at the top no longer applies.
