I use two Alphas on one circuit run. But, I have to plug & unplug

on which amp I'm using. Here's a question for the NEC experts out there.
Since I only use one amplifier at a time, can I parallel the existing socket
in the shack to another one located next to it? Yes, but why not just use a
duplex 240v recept.? My gut is telling me that
if two 20-A sockets are hot and active that NEC will require that each
socket have the capacity to simultaneously supply 20-A from each socket --
which will force me to make another home run of cabling back to the load
center...No, they can be treated just like 120v outlets
Which brings me to a second question. Under NEC, can the two home runs of
cabling be paralleled at the load center instead of the shack onto one
breaker as long as the breaker is sized for the capacity of just one home
run? NO, unless the wires running back to the panel are > 1/0Or, does NEC
specify two completely different paths, including
sockets, cable runs AND breakers back at the panel? Right! unless the wires
are > than 1/0
No wires can be paralleled that are smaller than 1/0.
