Electrical capacity is the maximum power the service panel can supply at one time. Electrical power is measured in watts, but power is the product of voltage and current. Electric service providers supply 240 volts of electricity to your home, but this does not mean the voltage remains constant. The voltage can fluctuate between 210 and 250 volts from time to time, depending on how the loads flow through the .From the top of the meter base will usually have two 2 1/2 inch stacks going up through the roof or up the side of the house.This is so they can double the ampacity coming into the meter base to give you the 400 A.We typically install these larger services on home exceeding 4000 sq ft.

Having two circuit breakers in a house is very very unrealistic, and probably not what your mom meant (she probably meant two boxes).Electric meter inspection & repair home page. This article discusses the visual inspection of electrical meters & meter bases & explains how to estimate the electrical service size, (or "electrical power" or "service amps") at a building by visual examination of the service entry cables, electric meter and meter base, electrical service panel, main switch, & other details. The electrical panel, or breaker box, is the heart of a home’s electrical system. Many older homes were built with 60-amp panels, which are often inadequate for modern electricity usage. Today, 100-amp and 200-amp panels are standard, with 100-amp typically sufficient for homes up to 3,000 square feet.
Residential electrical service is single phase (3-wires, 240V) more than 99% of the time. But there is that rare exception to watch out for. If the house is from the mid-20th century, it may still have a type of three phase service called “high-leg delta” (4-wires, 208V), which was necessary for air conditioning compressors of the era; or, it could be a newer home built for a . T he volume of electricity delivered to your house by the electrical utility company is measured in amperes, or amps for short. This has a direct impact on the various electrical panel box sizes available. Amperage can vary, from 30 amps, in very old houses, to 400 amps, when the houses are very large and consume a lot of energy.
