 The 1/8 volt 3 phase feed (8 volts hot to hot) does not have a high leg so the feed wires can be connected up top in any order The 1/240 volt 3 phase high leg feed wires have to be arranged in the correct order at the top of the panel in order that the 1 volt hot to neutral legs match up with the breaker slots down belowThe long answer is the following Single phase power that typically comes to a home has two hot legs of 1v each You can use either leg to power 1v devices or combine both hot legs to power a 240v appliance or motor (eg for a wellpump) This power is all 60Hz Three phase power has three hot legs, each of 1v

120/208 panel wiring- You do not put the 8 to any leg 1/8 wye does not have a high leg and you will get 1 to neutral on each leg, and 8 across any 2 legs We use red, black, and blue for 1/8, and brown, orange and yellow for 277/480 volt, but that is not in the code bookOverview Panelboard Interior, 400 Amp, 8Y/1V AC, 4Wire, 3Phase, 10 kAIC, 42Space, 42Circuits, Aluminum Bus, Breaker Type BAB Main Breaker/Lug Provision on the Top of the Interior, FeedThrough Provision on Bottom of Interior ***Custom Built for Platt Sales and use with 72" Can & Trim*** *** Item is in Manufacturer Allocation

Click "Add to Cart" to buy Eaton PRL1A3225X42CS Panel Board, Interior, I’m replacing a timer based contact for a restaurants outdoor building lights, sign, and parking lot lights The panel feeding the old timer contact equipment has a black phase, a red phase, a neutral and a ground Each leg has 1 volts to Refer to the panel schedule shown above The nominal voltage between the breaker in space 4 and the neutral bar is ___ volts Answer is 8 The diagram shows 1/240V 3 phase, 4 wire panel Spaces 2 and 4 are on a 2pole breaker the load is 45KVA The load has little bearing on this question

 1/8V Single Phase Power 1/8V single phase is derived from 8V three phase power If viewed on an oscilloscope, the three voltage waveforms on the three “hot” conductors all peak at different times each one is 1 degrees behind the next When using 1/8V single phase, you will use any two of those same three hot conductorsThe following figure shows a typical breaker box panel for 1V and 240V circuits There are three wires entering the main panel from the energy meter viz Hot 1 or Line 1 = Black Color Hot 2 or Line 2 = Red Color (for illustration purpose only) Neutral = White Color Click image to enlargeHttp//wwwelectricalindustrynetworkcom In this video I am describing how a 3 phase panel is built and how the bussing works in accordance w/3 phase power

 In a 3 phase panel you need to particularly select a 1/8 doublepole breaker, as opposed to just a 8 doublepole breaker 4) Wire the two remaining phase wires to the double pole breaker 5) At the outlet box, install two seperate A outlets One on each phase, sharing neutral and ground between themIn 1V, 8V and 240V, 1Phase & 3Phase, high leg delta wiring systems,, the available voltage levels are as follows inside the main breaker panel Voltage between three hot wires (hot 1, hot 2 (high leg delta) & hot 3) = 240V Three Phase Voltage between any two hot wires =
