Leviton 52120-CM2 120/240V AC Single-Phase 3-Wire and Ground, Home Automation Model with Surge Counter

love yours today I'd like to do an explanation on 120 240 involved single phase three wire services it's a very controversial topic on YouTube right now so someone's probably gonna run to the dislike button now but since I have a litany of these transformers I thought I would wire them up to simulate a residential service but before I do that let me just explain how these transformers work as you can see one single Bush ring on top which is where in this case since this is a thirteen point two cavies transformer a seven six 20 volt line would come in and then go to ground single-phase but there are three low-voltage bushings each are 120 120 240 a lot of people refer to this as the center tap however this is not a center tap in the transformer on transformers larger than 100 kV a so usually 167 KVA and above they'll be bushing here and then two bushings here and the other one on the end
