[TheForge] Capacity of Electrical wire

[Dan Brewer]

Tig welder 80 amp draw
Mill 20 to 30 amp draw
I would put in number 00 wire.  Remember to put in a disconnect in where the
machine is tied in.  You should probably put in a sub panel and then go from
there.  At the sub panel you will need 2 six foot grounds driven in at least
six foot apart.  If you shop is metal tie the shop in at several points
also. Look for some "no ox 2". No ox 2 is a protective covering for
electrical connections to ground.  The power run should be in conduit
between the meter and the sub panel.  Because of the size of the wire it
should be around 3 inch.  I would put in a quad out let every 8 feet along
the wall at the 4 feet off the floor.  This way no matter where you position
something you have power.  If you run the light power in to duplex outlet
hooking up lights will be easier.

Question is what is the total amps draw? Also do not put the machine or the
welder on the same circuit as the lights
At 125 you have a small volt drop if you don't go the next size wire bigger
