Arc-faults may occur anywhere
in a home as a result of:
- Worn
electrical insulation or damaged wire
- Misapplied or
damaged plug-in appliances and equipment
- Loose
electrical connections
Standard circuit breakers protect
wires from overload and short circuit conditions. The Siemens and
Murray Arc-Fault Circuit Interrupters provide the additional
protection of detecting arcing faults (an unintentional arcing
condition in a circuit) that standard circuit breakers are unable
to detect. An arc-fault interrupter is a device intended to
provide protection from the
effects of arc-faults by de-energizing the circuit when an
arc-fault is detected.
This additional protection makes
homes safer. The 1999 National Electric Code, Section
210-12, requires all 15 and 20 amp, single phase, 125 volt branch
circuit receptacle outlets installed in bedrooms to be protected
by arc-fault breakers. This NEC requirement will become
effective for new construction beginning January 1, 2002.
Even though not mandated until January, arc-fault interrupters are
available from our stock now to improve the level of protection on
new and existing dwellings.

Technical
Specifications
Siemens and Murray
AFCI circuit breakers are UL listed per Standard 1699 to meet the
requirements of the National Electric Code Article 210-12.
In addition to sensing and reacting to protect wiring from
overloads and short circuits, the AFCI will detect and trip the
circuit breaker when an arcing fault occurs.
Note: The
AFCI white neutral line (pigtail) must be connected to the panel
neutral for the device to function. Both the load power and
load neutral conductors are terminated at the circuit breakers. |
