This installation guide applies to the special Compact version of the LifeGuard GFCI which
meets the following requirements:
• 20 A rated load current
• Line-to-line voltage of 240 VAC or below
• Have option "6" or "20" for trip level and utilize the RCMA426H ground fault module
• Push button type front only (no digital display option)
For standard LifeGuard GFCI models, consult document NAE108011. For LifeGuard GFCIs with

Installation
Mounting - NEMA 4X Polycarbonate Enclosure
The standard enclosure for LifeGuard series GFCIs is a NEMA 4X polycarbonate enclosure. The
enclosure includes mounting feet and separate instructions on wall-mounting the enclosure.
Refer to these instructions for more infromation. Refer to figure 1 below for dimensions.

If the LifeGuard GFCI was purchased without an enclosure (backplate only), consult the follow-
ing section "Wiring, " as well as the section "Backplate Only Models" on the reverse side of this
document for additional mounting and wiring requirements.
Wiring
The GFCI is installed in series with the main circuit. Connection of the main circuit conductors
varies based on quantity of conductors and system voltage. In general, the following steps
must be taken:
• All active conductors, including the neutral, must be
brought into the device and landed on the provided
terminals.
• All active conductors are then brought out from the
load side of the contactor to the load / remaining
branch of the circuit.
• The ground wire is landed on the ground terminal
on the backplate, and brought out the load side.
The ground wire is NOT routed through the current
transformer.
