combining smaller gauges

Hello everyone,

Is it acceptable if when I run wire that I can combine multiple gauges to create a higher amp rating. So if I need to have a 50 amp 240v outlet to run something big and in the workstation I have available to me a total of two 30 amp 240v lines. Can I combine the two 30 amp 240v lines on a single 60 amp 240v breaker to supply the 50 amp 240v outlet.

Thank you

Not by code. The wires need to be at least 1/0 before they can be paralleled.

Ok. That is what I thought but figured maybe I would get lucky.

Something else. A 6 gauge wire can handle 60 amps correct. Well for some reason the extension cords that are 6 awg are only stated for 50 amps. What is up with that? Perhaps it has something to do with the length of the cord in addition to the length of the cord that is from the panel to the outlet. Well, if the outlet is right at the panel could I get 60 amps from a 6 awg extension cord that is only 25 feet long.


Thanks for helping

Different insulation types affect the ampacity of cables and wires.
