This size panel is well suited to most average to larger size homes, allowing the homeowner plenty of leeway to add a hot tub, additional outlets, etc. This panel may not be adequate for homes of 3,500 sq. feet or larger, especially if the home has electric appliances, water heater and there is dual air conditioning system, hot tub etc.

In homes exceeding 3,500 / 4,000 sq feet it is not uncommon to see two panels, a 200 amp panel and an additional 100 or 200 amp panel.
