Expert Analysis

This new section requires at least one 125-volt, single-phase 15- or 20-ampere rated receptacle outlet to be installed within 50 feet of service equipment. Although many engineered designs often specified a receptacle outlet in these locations, it was never a requirement of the NEC. Information provided in the substantiation indicated that this change was proposed for the same reason that a receptacle is required for servicing HVAC equipment as provided in 210.63. These receptacles are often needed for connecting portable electrical data acquisition equipment for the essential and qualitative analysis of the electrical system along with testing and servicing the electrical equipment. Presently, to accomplish the connection of such instruments and other tools, extension cords are run through doors, windows, or other openings throughout the building and often connected to non-GFCI-protected receptacles creating other hazards for personnel. This new section is an improvement in the NEC and an enhancement in safety for personnel. It should be noted that this general requirement does not specify that these required receptacles be protected by ground-fault circuit interrupter (GFCI) protection. The GFCI requirements in 210.8 would apply to receptacles required by this section if they are installed in locations specified in 210.8.
 

Surge Protective Devices for Service Equipment

In areas where sensitive electronic equipment is utilized, Leviton recommends the use of a Type 3 Surge Protection Receptacle.
Leviton’s Surge Protection Devices can be used individually or as part of a coordinated application strategy to protect sensitive electronic equipment, in industrial, commercial and residential locations.  Damaging voltage transients are diverted away from sensitive micro circuitry, providing protection against catastrophic failure, costly downtime and data disruptions.  UL 1449 Compliant.
