I know this forum is for circuits. However, I have a electrical related question. Most new homes have two 110 volt lines coming in and the phase difference between the two lines is 220v. All of my electrical equipment including air-conditioner and dryer are 110v.
I know I can take the main circuit breaker cover off and check the voltage with a voltmeter. However, I am looking for an option that does not require me to open the circuit breaker box.
How to check if my home already has 220v coming in without opening the circuit breaker box?
All of my wiring is underground. No over-head supply lines. Even the step-down transformers are in secured and locked distribution boxes throughout the neighborhood.
