For the majority electric panel installation, the price is between $850 and $ 2,500. The price will vary in line with the amperage capacity your household demands, and if you are repairing or replacing your electrical panel. National Electric Code (NEC) requirements for electrical panels are established by both Occupational Safety and Health Administration (OSHA) and National Fire Protection Association (NFPA). In order to prevent electrical shocks, heat build-up, and fires, your electrical panels must follow safety and health regulations.
