240 volt breakerReport
Please briefly explain why you feel this question should be reported.
I installed a 40 amp stablok breaker in my main panel.I hooked up the red wire on the one lug and black wire on the other lug, and the ground on the ground bus bar..When i check each wire on it’s own red to ground i get 120, black to ground i get 120. But when I check them together i don’t get 240 like i’m expecting, do you know why that is?? I check an existing 40 amp breaker in the panel, and when i check the red and black together i get 240.. But the new one will not, but individual lines are hot???
