If I have a 10:1 step down transformer (standard 120v to 12v doorbell xformer) can I attach it the 120+ and 120- on my split phase 240v and get 24v AC at the output.
I ask because I need to actuate a pair of relays that require 24v ac (to turn on 240V mains) and I would rather not have to find a 5:1 transformer and connect it between a single 120V line and the ground.
