Wiring for the Grizzly 1023SL Help
I need to run a 20 amp 240V line to the garage for the new 1023SL. I
have wiring experience having finished my basement and run numerous circuits for lighting, outlets, etc. Wiring for 240 doesnt look any more difficult than 120, just more wires correct? I need to purchase a plug for the saw and a matching outlet along with breakers. What about the wire? With a 20 amp circuit do I pull two 12g wires or is there a dedicated insulated wire with four leads? Matt |

Assuming 20A is enough, then you just need to run standard 12-2 romex. I'd suggest NEMA 6-20 receptacles (which can take both 15A and 20A plugs), and a 6-20 plug. If you want to get fancy you could use the twist-lock versions of the above. I'm a bit uncertain about whether 20A is sufficient though...the manual says the motor is rated at 18A, which would normally require more than a 20A breaker. Someone with more electrical code knowledge should pipe up here. Chris |

I too thought that might be a bit small but I have yet to trip mine. Cheers, cc |

That said, I prefer to pull 10/2 when installing 220 circuits in the shop .... that way if I want to upgrade that circuit for another tool, the wire is already there. One other thing to watch for: if your panel/sub-panel takes half height breakers, make sure that you use a slot for the 220 c'brkr that spans both hot legs ... you'd be surprised how many electrician's fail to do that on occasion. -- www.e-woodshop.net Last update: 2/20/07 KarlC@ (the obvious) |

I was going to duplicate the wiring for the dryer and range. Matt |

The best way for you to understand that is to go to your favorite hardware store or home center, and take a look at one of the breaker boxes on display, that doesn't have any breakers in it. You'll see immediately. -- Regards, Doug Miller (alphageek at milmac dot com) It's time to throw all their damned tea in the harbor again. |
