Most residential homes in the US, and certainly the ones in Portland, have a main electrical line coming in from their power company to a meter on the outside of their house. This “line” actually consist of two 120 volt wires and a neutral wire. In the electrical biz, these two 120 volt wires are called “hot” wires. From the electrical meter, the wires are routed into a main distribution area called an electrical panel. Depending on the size or electrical load of the home, you could have additional panels off the main one called “sub panels”. If you’re old school, you may call this panel a fuse box. Inside your main electrical panel are safety devices called circuit breakers, or if your home is old school too, fuses. You will have a breaker (or fuse) for each circuit in your home. These circuits are called branch circuits. A typical branch circuit might feed all the outlets in a bedroom for example. Most circuits in your home carry one hot leg of 120 volts, a neutral wire and a ground wire and are named, conveniently enough, 120 volt circuits. Other circuits carry two wires, each with 120 volts, and feed large appliances like your stove, water heater or air conditioner. These circuits are called 240 volt circuits.
