2009年7月11日 · When installing a NEMA 14-30 device, such as your dryer receptacle, the terminals should be marked W X Y and G. If you were installing a NEMA 15-30 device, which does not have a neutral, the terminals would be marked X Y Z and G. In each case, the X Y or Z terminals designate "hot" lines.

2012年9月27日 · I have a question about the wiring of 208V/3 phase outlets. I believe that the wiring color code for 208V/3 phase is L1 => Black, L2 => Red and L3 => Blue (along with Neutral => White and Ground => Green). However, outlets are usually labeled X, Y and Z, rather than L1, L2 and L3. Depending...

2011年9月20日 · with a typical NEMA 10 series receptacle, you connect the Hots(black/red etc) to X and Y, and neutral only to W. W most of the time will have a different color screw from X and Y(should be silver, hots brass). the ground wire if you have it should be connected to the metal box if present, or capped.

2012年1月17日 · Problem: Smaller generators tend to have only a 3 prong 120v receptacle, which don't play well with the 4 prong power transfer box. I thought of simply making a 3 wire to 4 wire cable & "jump" the x & y leads to give 120 to both sides of the panel. Of course, the well pump would HAVE to be off for this to work.

2012年6月20日 · When the appliance lists two voltages (x/y), it usually means it requires BOTH voltages to operate, NOT EITHER one (x) or the other (higher) . It's like saying, you require cold AND hot water at your sink faucet, however you need only cold water to your toilet, and only hot water to your dishwasher... A 208v socket may have just 208v and not 120v.

2024年4月7日 · I know if you have a GFCI, you need your load and line matched correctly. But if you have a 2x hot wires and 2x neutral wires, do you need to match the hot with the neutral from the wires in the walls? Two brass screws for the hot, two silver screws for the neutral wires. Do you need to match...

2023年9月29日 · In the code above, you can replace the x_toilet, y_toilet, x_shower, y_shower, x_vanity, and y_vanity variables with the actual coordinates of the respective elements in your layout. The calculate_distance() function calculates the Euclidean distance between two points using the distance formula.

2011年6月15日 · Local code is 30" deep x 12" diameter sitting on top of a 2' diameter footer. I went down 4' and used 2' diameter sonotubes all the entire length to about 4-6 inches above grade. The bottom of the deck is about 11 ft about grade and I used two pressure treated 8x8s attached to galvanized plates with 12 or 18 inch j-bolts going into the concrete.

2022年4月12日 · You only need to have to use both y terminals when you have 2-stage cooling. For heating, to get the full benefit of 2-stage, the long cycles on low fire bringing on high only when needed, 2-stage thermostat and wiring is needed.

2007年1月4日 · For every 'X' Btuhs, you will need 'Y' cubic feet of space in the adjacent area in order to consider it “unconfined” ('X' and 'Y' vary per local code). And then if you determine that the adjacent area is considered “unconfined”, then you will also have a minimum free area of vent (a wall grille, louver, hole, whatever) that you have to ...
