How do I determine the electrical capacity of my home? Will it handle my requirements?
The electrical service provided to a home is measured in amps, which is a measure of the “flow rate” of electricity through a wire. Today’s average home is constructed with electrical service of 100 amps, which means that the large main wires entering the home can safely handle 100 amps of current before there is a risk of overheating.
Some homes, however, are built with 200 amp service, while homes built prior to the 1950s featured a 60 amp service. In order to determine the electrical capacity of the home, a home inspector will check the size of the wires entering the home to verify they are compatible with the main electrical disconnect (breaker or fuse). Modern homes are equipped with breakers to detect if too much current is flowing through the wires. The breaker will shut off to prevent overheating of the wire, which is a potential safety hazard.
A home’s electrical capacity is dependent on the demand within a home. The more electrical fixtures and appliances there are, the larger the service requirement. Appliances with the highest demands include stoves/ovens, dryers, and electrical water heaters. Saunas, spas and workshops also draw large quantities of electricity. If many of these appliances are operating at the same time, the electrical service may be inadequate, causing the main breaker or fuse to trip.
