If you have recently purchased a home with an older panel or your current panel cannot supply the amount of power you need, then you might need to upgrade the panel or install a new one. The minimum requirement for an electric breaker panel is 150 amps. Panels come in 100, 150, 200 and 400 amp capacities. Old panels, especially those with the old glass fuses, are prone to tripping and can pose a fire hazard. Remember to choose a panel that exceeds your electricity needs so you won't tax your electrical system, which can cause outages, or worse, a fire. Your electrician can advise you on whether your panel can be upgraded or needs to be replaced. Upgrades will cost you about $ 1800.00 on average. Keep in mind that an old style fuse box cannot be upgraded and must be replaced with a new panel.
