Feed-Through Panel: Feed and Load Wiring

• Use a trough when the switching panel is far away from the distribution panel. Splice neutrals in trough.
• Wire the switching panel similar to a lighting distribution panel. Run feed and load wiring.
• Use the switching panel to provide temporary lighting by leaving the bypass jumpers in place. (See page 16 for
more details.)
Wire Sizes
• Power Feed (Hot/Live):
#14-#10 AWG (2.5-4.0 mm
• Switched Hot/Live:
#14-#10 AWG (2.5-4.0 mm
Control Circuit Power:
• Supplies power for internal operation.
• Requires dedicated feed with same
voltage and phase as panel.
• Must be 1/4" (6 mm) away from
PELV (Class 2: USA) control wiring
harness.
• Panel voltage (see pages 2-3)
indicates feed voltage.
• For 230 V and 240 V
"Hot" is referred to as "Live".
Therefore, terminals will be labeled L
and SL.
Dual-Voltage Panel: Feed and Load Wiring (120/277 V
Wire to either the
120 V or the 277
V control feed
terminals, not both.
The terminals for the
unused voltage will
remain empty.
*Note:
120 V Hot/Live
terminal is protected by
an internal fuse in case
277 V is mistakenly
applied. A spare fuse is
also supplied in the panel
terminal block.
