Abstract: The portable electrical power box includes a power extension cord connected to a 240-volt input plug. Via the input plug, the device plugs into a 240-volt outlet in a home or other location where split phase power is available. Two branch circuits comprise 120-volt receptacles disposed on the power box. The power extension cord has a neutral wire, a first split voltage wire, and a second split voltage wire. The neutral and first split voltage wire feed voltage to the first branch circuit of receptacles. The neutral and second split voltage wire feed voltage to the second branch circuit of receptacles. This arrangement minimizes overloading electrical panels in homes with extension cords in the home's 120-VAC outlets. The device has circuit breakers to prevent overloads.
