How many 220v duplex outlets we connect to a single circuit or to a breaker of 20A.?and will the size of wire will be same for 110v and 220v.? I.e 12awg. <br /><br />Thanks.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5703009255391882847.post-59602821171361805542012-04-09T11:08:33.062-07:002012-04-09T11:08:33.062-07:00Hi, Tim,
Sounds like you have it correct. The wi...Hi, Tim,<br /><br />Sounds like you have it correct. The wires going to the saw just continue on to the 110V GFCI receptacle (a parallel connection).<br /><br />There are 220V GFCI receptacles and you could install a plug on your bandsaw, wire a 220V GFCI receptacle and plug it in. I didn't do that and it isn't required here.<br /><br />The way GFCI works is to monitor the current in the two current-carrying wires (the two hots for 220V or the hot and neutral for 110V... yes, neutral definitely carries current; it's poorly named). The current in one wire should always equal the current in the other. A GFCI receptacle monitors that and trips when they are not equal. When they are not equal, the current is going somewhere and that somewhere is ground, hence a ground-fault.<br /><br />About your question about "does the hot that goes to the saw have to go through the load on the GFCI". No, definitely not. The current source attaches to the GFCI's "line" side and your protected devices are plugged into the "load" side; you don't want any part of the wiring skipping over from "line" to "load" side.HalfInchShyhttps://www.blogger.com/profile/04633026047989713624noreply@blogger.comtag:blogger.com,1999:blog-5703009255391882847.post-15388065703747488802012-04-08T11:29:28.146-07:002012-04-08T11:29:28.146-07:00Hi,

I wired the 220 direct inside the duplex box, no receptacle, and put in a 110 GCFI receptacle like you suggested. One of the hots goes direct to the saw and one goes to both the saw and the plug, neutral goes to 110 and ground goes to both. For GCFI to work properly, does the hot that goes to the saw have to go thru the load on the GCFI like chaining 110s or can it be pig-tailed? I went with pig-tail as I don't see how GCFI works in conjunction with 220 because there is no neutral. Your thoughts would be appreciated.<br /><br />TimAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-5703009255391882847.post-89985984788539119252012-01-05T20:48:21.550-07:002012-01-05T20:48:21.550-07:00Thanks Paul.

What goes into the box on the saw st...Hi, Michael,<br /><br />What goes into the box on the saw station is a pair of hots, a neutral, and ground. The 220V socket gets the two hots on its terminals as well as the ground. The 110V duplex socket gets one of the hots (either one) to its hot (the brass terminal) and the neutral (to the aluminum terminal) as well as ground. All you're doing with the 3 conductor + ground wire going to the saw station is bringing the rails at the subpanel out to the saw to make your connections there.<br /><br />If you mean "double duty" because it goes to two sockets, yes, and that's normal. In your home's wiring, a hot and neutral go to one socket then a cable runs from that to the next to the next and so on in a string. You are basically creating that inside that box.<br /><br />Very very handy; when I shoot video, I often unplug the light that goes above the saw to plug in a softbox diffuse light for the camera.<br /><br />If the following doesn't make sense depending on your electrical knowledge, just ignore it: it describes a different wiring scenario you could use, but don't have to use:<br /><br />In my case, the 110V duplex socket is a GFCI protected socket (a master); that's always a good idea. If instead you used GFCI-protected <i>breakers</i> in your subpanel, you wouldn't (can't!) use GFCI sockets (double protecting doesn't work properly).<br /><br />If you had a GFCI-protected <i>breaker</i> on that circuit, you could even split the 110V duplex socket. There's a bridge between the two sockets that can be removed. Remove it on the hot side (brass side). Now run one hot to the top socket, one to the bottom. Neutral still goes to the other side as well as ground to ground. Now what you've done is put the two sockets on opposite rails better balancing current in the neutral line. Isn't a big deal, but thought to explain it.HalfInchShyhttps://www.blogger.com/profile/04633026047989713624noreply@blogger.comtag:blogger.com,1999:blog-5703009255391882847.post-80794095951257263742012-01-03T21:35:57.177-07:002012-01-03T21:35:57.177-07:00Great way to reduce cords across a shop.

I count 2 hot wires going into the duplex box but 3 connections. Is one hot pulling double duty...connected to the 110 and 220?

With my understanding of electrical wiring I wouldn’t attempt installing a ceiling light fixture, but after reading your article I might even attempt such a thing as you’ve explained. I also appreciated the cost saving comments as well. I’m looking forward to a write up on your subpanel installation. <br /><br />DeanAnonymousnoreply@blogger.com
