When the unit MOCP device value exceeds 60-A, unit-

circuit. These fuses are included in accessory single point
boxes, with power distribution and fuse blocks. The single
point box will be installed directly under the unit control box,
just to the left of the partition separating the indoor section
(with electric heaters) from the outdoor section. The single
point box has a hinged access cover. See Fig. 36. The sin-
gle point box also includes a set of power taps and pigtails
to complete the wiring between the single point box and the

All fuses on RAV units are 60-A. (Note that all heaters are
qualified for use with a 60-A fuse, regardless of actual heat-
er ampacity, so only 60-A fuses are necessary.)

SINGLE POINT BOXES WITHOUT FUSES

Unit heater applications not requiring supplemental fuses
require a special single point box without any fuses. The
accessory single point boxes contain a set of power taps
and pigtails to complete the wiring between the single
point box and the unit's main control box terminals. Refer
to accessory heater and single point box installation
instructions for details on tap connections.
