2000 100A Ferroresonant Rectifier J85503A-1
Issue 6 October 1998
Installation 5 - 3
Figure 5-1 shows the ac input conduit hole and alternate hole and
termination points for the ac input wires and the “green wire”
ground. This wire is the ac equipment ground (AC EG), also
known as frame ground (FRAME GRD).
Table 5-A shows the recommended customer-supplied fuse size
and type for the branch circuit protection in the ac service panel
supplying input to the rectifier. The types shown are
BUSSMANN

fuses. Equivalent UL listed fuses or circuit
breakers can be used in lieu of those shown. If circuit breakers
are used, they should have trip elements of an equivalent rating
to the recommended fuse.
The AC EG or frame ground is normally connected using the
mechanical connection provided. Discard this connection if you
prefer the T&B
2
crimp connection also provided. See note 61 on
J-drawing, J85503A-1.

* Input wire count includes “green wire” ground. Use KS-24194 L3 or 75°C commercial wire.
† Where the trade size of the conduit used is smaller than the trade size for which the conduit knockout
was sized, use appropriate knockout reducing washers.
