Can a house have two breaker boxes?
Overwiring is a sort of trick to get more mileage out of the main breaker panel. The panel might look normal at first glance, but it contains tandem breakers that allow two circuits to use one slot. Tandem breakers are different from double-pole breakers, which use two slots in the panel.

How electricity works in your home?
Electricity arrives at your house from your local utility company by a power line or underground though a conduit. Most homes have three-wire service—two hot wires and one neutral. Current begins at a power source, powers the appliance or device along the circuit, and then returns to the power source.
