1) NS Appliances have in-out wiring terminals
that accepts two #12 to 18 American Wire
Gauge (AWG) wires at each screw terminal.
Strip leads 3/8” inches for connection to screw
terminals.
2) Break all in-out wire runs on supervised circuit
supervision as shown in Figure 7. The polarity
shown in the wiring diagrams is for the
operation of the appliances. The polarity is
reversed by the FACP during supervision.
MOUNTING OPTIONS:
CAUTION:
The following figures show the maximum number of field wires (conductors) that can enter the backbox used with
each mounting option. If these limits are exceeded, there may be insufficient space in the backbox to accommodate the field wires
and stresses from the wires could damage the product.
Although the limits shown for each mounting option comply with the National Electrical Code (NEC), Wheelock recommends use of
the largest backbox option shown and the use of approved stranded field wires, whenever possible, to provide additional wiring room
for easy installation and minimum stress on the product from wiring.
