Power enters our homes as 240v with a center tap (called neutral).
In our circuit breaker box the two hot lines (L1 and L2) have 240V
between them, this is sent out to dryers, ovens, water heaters, and
HVAC. Then for the the 120v lines L1 and neutral (plus a ground wire)
are distributed to lights and outlets, The same is done with L2 and
neutral. There is an attempt to keep the load on each leg somewhat
equal. These 120v lines generally have a 20amp circuit breaker and use
12 gauge wire, some very old homes have 15 amp breakers/fuses and 14
gauge wire.
