Parallel Feeder Question

[pitkas]

Is it permissible to run parallel feeders in the same conduit? I have 2 -2 1/2" nipples between CT can and disconnect. If I increased the nipple size (6" nipple) to 4" I can run all the conductors in one conduit. I can save an EGC and 2 hole punches. Any thoughts?

Yes it's fine, also a nipple (raceway 24" or less) can be filed to 60% instead of the typical 40% for more than two conductors. Depending on the conductor size you might not even need a 4" nipple. Another advantage of the short nipple no derating applies either.

My EGC's start at the service disconnect. Everything before the service disconnect, I call bonding jumpers. Maybe I'm wrong though....
