a) one 20amp circuit
b) one 15 amp dedicated circuit
c) one 20 amp dedicated circuit
d) one 20 amp dedicated circuit GFCI protected.
ICC answer is "d".....
I say the answer is "b" because of 1189va/120=9.8 amps, round up to 15 amps ...
From the 2006 IRC. (underlining is mine)
- E3602.3 Fifteen- and 20-ampere branch circuits. A 15- or 20-ampere branch circuit shall be permitted to supply lighting units, or other utilization equipment, or a combination of both. The rating of any one cord-and-plug-connected utilization equipment not fastened in place shall not exceed 80 percent of the branch-circuit ampere rating. The total rating of utilization equipment fastened in place, other than lighting fixtures, shall not exceed 50 percent of the branch-circuit ampere rating where lighting units, cord-and-plug-connected utilization equipment not fastened in place, or both, are also supplied.
... as well as E3802.5 exception not requiring GFCI protection....
- E3802.5 Unfinished basement receptacles.All 125-volt, single- phase, 15- and 20-ampere receptacles installed in unfinished basements shall have ground-fault circuit-interrupter protection for personnel. For purposes of this section, unfinished basements are defined as portions or areas of the basement not intended as habitable rooms and limited to storage areas, work areas, and the like (see Section E3802.11).
- - Exceptions:
- - - 1. Receptacles that are not readily accessible.
