  • We specialize in essential electrical code updates. The National Electrical Code (NEC) sets electrical standards for the safe installation, design, and inspection of electrical wiring. The code began in 1897 and is updated by the NFPA every three years to help reduce fire hazards and accidents. Many homeowners don’t realize ground fault circuit interrupter (GFCI) requirements have gotten stricter, reducing residential electrical shock incidents. Staying informed on electrical code updates helps homeowners and business owners know how to protect their properties better.
