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.
