estesbubba Posted October 10, 2014 Report Share Posted October 10, 2014 I have the Grizzy G0441 cyclone and running 8-2 with ground romex to it since the manual calls for 40 amp circuit. The manual suggests wiring into a disconnect switch but any reason I can't just put a 40/50 amp socket and run a plug? My breaker box is 10' away so I can easily disconnect power there. The wire running from the control to the motor is 12 gauge which surprised me for a 40 amp requirement. If I can run a plug to a socket, do I use 12 or 8 gauge to it?

wdwerker Posted October 10, 2014 Report Share Posted October 10, 2014 Socket should be fine. 12 gauge cord only if it is very short. 10 gauge should work fine for a 6 ft cord. Quote Link to comment Share on other sites More sharing options...
wtnhighlander Posted October 10, 2014 Report Share Posted October 10, 2014 Manuals call for disconnect switches for safety / liability reasons. They want you to use a device rated for disconnect under load in case you need to kill that line while it is running. A plug will generally NOT be rated for disconnecting under load, and doing so can result in a dangerous arc flash. Don't make a habit of using the circuit breaker to kill power under load either, as that can quickly shorten the life of the breaker and cause it to fail. Having said all that, I would probably still just use a plug. Quote Link to comment Share on other sites More sharing options...
tim0625 Posted October 11, 2014 Report Share Posted October 11, 2014 I'm +1 with Steve and the Highlander....be sure of the rating on the plug. With a cyclone, I don't really see why you'd need to interrupt the power under load which in my mind is 'while it is running' unless there was some sort of hang up in the impeller, you'd want to and you'd want to quickly! But having said that....This disconnect is $16.74 and at 60 amps, it's a little overkill but the disconnect doesn't act as the weakest link like a breaker anyway.....at that price, why wouldn't you put one in? I just know in that one moment that you might need it, it would be $16 well spent. On the wire, they probably ran a 12 gauge wire because of the short distance. If it were me, I'd just wire it to the box at what the manual said or go one gauge heavier on the 10 foot wire. Since this will be 220V, I'm thinking a 10/3 would be fine on the 40 amp circuit for 10 feet. Quote Link to comment Share on other sites More sharing options...
estesbubba Posted October 11, 2014 Author Report Share Posted October 11, 2014 Tim that disconnect says 60 amps but only 14 gauge wire Quote Link to comment Share on other sites More sharing options...
tim0625 Posted October 11, 2014 Report Share Posted October 11, 2014 Tim that disconnect says 60 amps but only 14 gauge wire Didn't catch that...yeah you'd need to go heavier but if heavier is still pretty cheap, may want to consider it.

wtnhighlander Posted October 11, 2014 Report Share Posted October 11, 2014 I think the spec "wire range 14-3" means it accepts wire from awg #14 up to awg #3. Quote Link to comment Share on other sites More sharing options...
tim0625 Posted October 12, 2014 Report Share Posted October 12, 2014 I think the spec "wire range 14-3" means it accepts wire from awg #14 up to awg #3. So it is heavy enough.... Quote Link to comment Share on other sites More sharing options...
