Single Point Boxes and Supplementary Fuses —
When the unit MOCP device value exceeds 60- - A,
unit- - mounted supplementary fuses are required for each
heater 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. 26. The Single Point Box also
includes 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 the accessory heater and
Single Point Box installation instructions for details on tap
connections.
All fuses on 558J units are 60- - A. (Note that all heaters are
qualified for use with a 60- - A fuse, regardless of actual
heater 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.
