If the compressor draws 20 amps, you will need a 30 amp cable to feed it.
That would be 10gauge wire. From what you describe of your shop, you would
do well to run a 6/3 feed from the main and install something like an 8
circuit sub panel in the shop, then run the machine outlets and lights from
the sub

I am going to have a 200amp. heavy up done , but later plan to add to
Garage/worshop area. What type of wire is suitable for use of air
compressor
rated @ 20amp. also would like to add overhead flurosent light, run power
saws grinder etc. Should I have dedicated circuits, please advise best
route
to go.
Thanks Woody2
