MOUNTING NOTES
Caution: The mounting options 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 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.
Caution: Check that the installed product will have sufficient clearance and wiring room prior to installing backboxes and
conduit, especially if sheathed multiconductor cable or 3/4” conduit fittings are used.
1. Mounting hardware for each mounting option is supplied.
2. Conduit entrances to the backbox should be selected to provide sufficient wiring clearance for the installed product. When
extension rings are required, conduit should enter through the backbox, not the extension ring. Use Steel City #53151 (1-1/2”
deep) or #53171 (2-1/8” deep) extension rings (as noted in the mounting options) or equal with the same cut-out area.
3. When terminating field wires, do not use more lead length than required. Excess lead length could result in insufficient
wiring space for the appliance.
4. Use care and proper techniques to position the field wires in the backbox so that they use minimum space and produce
minimum stress on the product. This is especially important for stiff, heavy gauge wires and wires with thick insulation or
sheathing.
5. Do not pass additional wires (used for other than the appliance) through the backbox “unless the backbox is of a sufficient
size to permit additional wiring as described in NEC 314.16 (B)”. Such additional wires could result in insufficient wiring space
for the appliance.
NOTE: Due to continuous development of our products, specifications and offerings are subject to change without notice in
accordance with Wheelock Inc. standard terms and conditions.
