I have seen something you have posted earler

This is everything that will be on the breaker box, with room for a
hair more.


Equip Voltage Amps Watts


Welder 230 27 6210
Compressor 230 20 4600
Tools Outlet 120 20 2400
Outdoor Lights 120 20 2400
Misc 120 15 1800


Total Watts 17410
First 10,000 Watts at 100% 10000
Remaining Watts at 40% 2964
Total Watts for AMP determination 12964


AMPS needed total watts / 230V 56.37


Thanks, James


I have a few questions, and comments. Any one who don't agree feel
free to set me strait. First thing the new welder will only use 47
amps when you turn it up all the way. Not that you would not want to
use it cranked up all the way, but when you do you can always turn the
compressor off. the next thing you have shown, but was not clear was
the 120v loads. The loads could be put on opposite phases so the load
will not be 40 amps when you have 20 Amps on the black phase and 20
amps on the red phase it will be 20 amps. How many horse power
compressor do you have if you take the horsepower and multuply it by
746 that will give you the ammount of watts. Just because you use a 20
amp breaker that doesn't mean that the circuit will automatically draw
20 amps it just means that the wire that runs to the load is protected
at 20 amps. And on the outside lights you would have to have alot of
lights burning to equal 2400 watts. If you take the ammount of watts
off the bulbs you plan to use that will help your equation out alot.
I am not wanting you to change your mind, just giving some food for
thought before you spend three thousand dollars on electrical instead
of more metal working equipment.
