Life Safety Loads Depend on Reliable Power Systems

What matters to a person when they are in a facility that has capacity for many people and an emergency situation such as fire, flooding, storms, earthquake, explosion, or merely loss of normal utility electrical power occurs? Naturally, this depends on the situation, but the basic human instinct is to want to escape the event without physical or extreme emotional trauma. We desire safety for our family, ourselves, and others.

Focus on the Code: Do washing machines require GFCI protection?

Thank you for your correspondence. There is no specific requirement in the NEC for the washing machine itself to have GFCI protection. Section 210.52(F) requires a receptacle outlet to be installed for the laundry area and it must be supplied by a 20-ampere branch circuit in accordance with 210.11(C)(2).

Selective Coordination – Responsibilities of the AHJ

Selective coordination ensures proper isolation and localization for all possible overcurrents (from overloads to maximum short-circuit currents at the point of application) to the nearest upstream overcurrent protective device and prevents unnecessary loss of power to other loads, especially loads essential for life safety.
