I have 8 dual bulb F32T8 fluorescent fixtures in soffits
illuminating my living room.
They are wired in parallel and
actuated by a 2-pole wall switch. I propose to rewire them so that one bulb of each fixture is on one circuit,
and the other bulb of each is on a second circuit. The wall
switch would become 3-pole:
low (power one circuit),
high (power both circuits),
off. To do that, I would
reroute one B+ lead (blue)
and one B- lead (red) to
a bulb in an adjacent box.
The high tension leads would run box-box in a flex steel conduit. The line voltage wiring would run through separate punch outs.
I'm aware that any jumper wiring would have to be 600DCV rated. The result
is 4 ballasts powering 8
tubes on one circuit, and 4 ballasts powering 8 tubes
on the other circuit, one tube in each box on circuit
A and the other tube on circuit B. Of course, they're really not separate circuits; they're joined at the switch. Are there any
code issues with this?
