It’s important to understand how a breaker panel works and how to calculate it. You can determine how much power you will need by computing your total load. Most buildings less than 2000 square feet use 100-amp panels, but larger buildings and appliances that consume high amounts of power might require a 200-amp panel. The size of your sub panel will depend on the size of your building, floor area, and expected load. A ground rod may be located far from the main electrical panel, so be sure to check local building codes. You must also install a buried jumper wire to connect the ground rods. For a subpanel with less than 200 amps, a 6-foot ground rod is sufficient. Some jurisdictions require a 3-wire ground rod, though. It must be at least six feet from the main electrical panel, or close to it. Here are some steps to follow before you get started.
This process will cost around $3,000, but you’ll be glad you did once you’ve paid the bill. If you intend to replace a 100-amp service with a 200-amp panel, you’ll need to redo the main breaker panel and add new wire from the street. Upgrading your home’s electrical service does not always require a permit.
