240 Vac Wiring Diagram


240 Vac Wiring Diagram - why do 240v circuits not require neutral they run a 240 v line to the plug wire two hot lines each to the hot on a different plug wire the one neutral line to both neutrals and you check the wiring diagram for what the device requires and if it says 240v 1ph or single phase thats just two hots and a ground and if the device says p div div class b algotextcarousel id ce carousel 1788893361 2 div id slideexp1 be7ee8c class b slideexp data wire i slideexp init b select i f selected o f active o data control id slideexp1 be7ee8 data appns serp data k 5385 1 data stk div class b overlay div id slideexp1 be7ee8chevrons prevbtn class btn disabled prev rounded bld data dir div class bg span span div div class vcac div style height 32px margin top 16px div class cr div div div div div div div id slideexp1 be7ee8chevrons nextbtn class btn disabled next rounded bld data dir div class bg span span div.

a device runs on 120v one ungrounded hot conductor and one grounded neutral conductor are needed if a device needs both 120v and 240v then two ungrounded hot conductors and one grounded neutral conductor must be used if you connect a load between the two ungrounded legs of the circuit you can see how you have a plete circuit through the coil if you connect a load between one of the ungrounded conductors and the grounded neutral conductor you can also get a plete circuit though it s only through half of the coil since these circuits only include half the coil the voltage is also half e s e p n s n p div div class b textcarouselfooter div class b bestanswer best answer div div class b separator 183 div div class b upvote img class rms img src data image svg xml base64 phn2zyb4bwxucz0iahr0cdovl3d3dy53my5vcmcvmjawmc9zdmciihzpzxdcb3g9ijagmcaxniaxnii 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.
