Thanks for the reply.

I am looking to the question to either plug it and draw the line, or open the box (if it is openable) and daisy chain the connection for the new line?. Are any code violations in either of the approaches I need to be concerned of ?

I think I run it to the garage and put a 30 amp outlet there (garage). If you add wire, it has to be sized to the breaker (or vice-versa) so either make the new wire the same size (probably #8) or change the breaker down to whatever you run….in which case you would want to pull that 40 amp outlet and cap that location. BTW, it sucks to work with #8 wire.

It’s a code violation to daisy chain and add a second outlet to that line. Circuits above 20A are to be dedicated. You can use a junction box and splice on more wire to run to the garage. The breaker can be no larger than the outlet it serves. If the saw calls for a 20A circuit, make it a 20A circuit. Also voltage is now 240V, not 220V.

I’d just change the breaker to a 240v 20A and run some 12AWG wire with a new outlet.

If the motor has a 20A limit and the breaker is sized to 40A, I hope your fire department is close by.

There is no danger running a 20A motor on a 40A circuit. The breaker is to protect the house wiring, not the equipment. The motor should have it’s own protection, either via an overload built into it, or in the starter used by the machine.

Thanks everybody for the good advice.

I saw the manual for G0513X2, and it draws 19A when wired for 110V, and only 9.5A when configured for 220V.

I did more research on local code and I was told inspectors will not approve if we tap from Circuits meant for Cooking Range or Dryer or such equipment. They need to be on dedicated circuit.

So, what I am planning is to draw a separator 240V line from main panel (yes, I do have some slots available) and protect that line with 40 AMPs breaker. On that line on the garage side, planning to install a sub-panel with 4 or more slots. This way, I can have both 240V line along with 110V lines, Good part is that my new 110V lines in the garage can be put on 12 gage wire and on 20 amps breaker in the sub panel. This approach solves my other problem of existing 110V outlets in the garage is only on 15 amps circuit and many times my compressor trip that line.

My bad, I concede, I forget that it’s mostly about wire gauge and length of the run. MrUnix is spot on, ignore my previous statement.

Well you’re calling 240V correctly, but half is not 110V, it’s 120V.

Have your say...
