Bryant ASPAS1BBA012 - Manual (Page 6)

Only qualified electricians or contractors should
attempt such installations, which must comply
strictly with applicable codes, standards and
regulations.
1.1 UNPACKING/INSPECTION
After unpacking, carefully inspect the contents
for damage.
• This standby generator set has been factory supplied
with a weather protective enclosure that is intended for
outdoor installation only.
• This UL listed standby generator set is packaged with
an automatic transfer switch with built in load center.
The combination transfer switch and load center is
pre-wired with a two foot and 30 foot conduit. Circuit
breakers for emergency circuit connections are
included.
• This UL listed, 2-pole switch is rated at 100 AC
amperes at 250 volts maximum. This transfer switch
is for indoor use only.
If this generator is used to power electrical load
circuits normally powered by a utility power
source, it is required by code to install a
transfer switch. The transfer switch must
effectively isolate the electrical system from the
utility distribution system when the generator
is operating (NEC 700, 701 & 702). Failure to
isolate an electrical system by such means will
result in damage to the generator and also may
result in injury or death to utility power
workers due to backfeed of electrical energy.
If any loss or damage is noted at time of delivery, have
the person(s) making the delivery note all damage on the
freight bill or affix their signature under the consignor's
memo of loss or damage.
If a loss or damage is noted after delivery, separate the
damaged materials and contact the Bryant for claim
procedures.
“Concealed damage” is understood to mean damage to
the contents of a package that is not in evidence at the
time of delivery, but is discovered later.
1.2 PROTECTION SYSTEMS
Unlike an automobile engine, the generator may have to
run for long periods of time with no operator present to
monitor engine conditions. For that reason, the engine is
equipped with the following systems that protect it
against potentially damaging conditions:
1. Low Oil Pressure Sensor
3. Overcrank
2. High Temperature Sensor 4. Overspeed
There are LED readouts on the control panel to notify
personnel that one of these faults has occurred. There is
also a “System Set” LED that is lit when all of the
conditions describe in Section 1.3 are true.
1.3 NEC REQUIREMENT FOR ARC
FAULT CIRCUIT INTERRUPTION
BREAKER FOR BEDROOMS
In 2001, the National Electric Code (NEC) introduced a
requirement for new construction. This new requirement
indicates the need for Arc Fault Circuit Interrupters to be
used to protect the complete branch circuit that feeds a
dwelling bedroom. The actual NEC requirement is
indicated below.
1.3.1 SECTION 210.12 ARC FAULT CIRCUIT
INTERRUPTER PROTECTION
1. Definition: An arc fault circuit interrupter is a device
intended to provide protection from the effects of arc
faults by recognizing characteristics unique to arcing
and by functioning to de-energize the circuit when an
arc fault is detected.
2. Dwelling Unit Bedrooms: All branch circuits that
supply 125 volt, single-phase, 15 and 20 ampere
outlets installed in dwelling unit bedrooms shall be
protected by an arc fault circuit interrupter listed to
provide protection of the entire branch circuit.
Section 210.12 requires that AFCI protection be provided
on branch circuits that supply outlets (receptacle,
lighting, etc.) in dwelling bedrooms. The requirement is
limited to 15 and 20 ampere, 125 volt circuits. There is no
prohibition against providing AFCI protection on other
circuits or in locations other than bedrooms. Because
circuits are often shared between a bedroom and other
areas such as closets and hallways, providing AFCI
protection on the complete circuit would comply with
210.12.
If during the installation of the Bryant Home Standby
system the decision is made to provide back up power to
a bedroom branch circuit, then the circuit breaker in the
Bryant Transfer Switch should be replaced with an Arc
Fault Circuit Interrupter.
It is most important that breakers only be switched like for
like. For instance, if replacing a 15A breaker, it MUST be
replaced with a 15A AFCI breaker. Likewise, a 20A
breaker MUST be replaced with a 20A AFCI.
These AFCI breakers are available at the nearest
electrical wholesaler or hardware store.
