APPLICATION

This digital GE Time Switch (15132) is a universal, electromechanical time 
switch which can be field configured for various power supply voltages. 
The voltage options include 120VAC, 208/240VAC and 277VAC – all within 
the same unit! Selection of the desired supply voltage is easily achieved 
by positioning dipswitches on the printed circuit board assembly (consult 
Dipswitches Configuration on back). The mechanism is mounted in a NEMA 
indoor or outdoor enclosure and is intended for the control of lighting, heating, 
air conditioning, pumps, motors, or general electrical circuits in residential, 
commercial, industrial and agricultural facilities. 
     

SPECIFICATIONS

Input Voltage: 

120 VAC, 208/240 VAC, or 277 VAC in all units based

INSTALLATION

CAUTION: Before wiring or servicing, power to this time switch and the 
equipment it controls must be turned off. Turning off the time switch only 
will not prevent a shock hazard. Replace cover plate within housing before 
supplying power to time switch. If you are not comfortable installing this 
device please contact a licensed electrician. Before installing this product read 
all instructions carefully.

Removing Knockout

1.  Select knockouts to be used. Remove the inner 1/2” knockout by inserting 

a flathead screwdriver on the inner most ring and carefully punching the 
knockout loose. Remove slug. If the 3/4” knockout is required, remove the 
outer ring with pliers after removing the 1/2” knockout. Smooth edges with 
a knife if necessary. 

Please refer to Quick Start Guide for Examples and More Details.

Mounting of the Time Switch Box

NOTE - Before mounting be sure to remove knockouts for the wires, (see Quick 
Start Guide)

1.  In order to mount the box you will need the 3 supplied anchors and 3 

supplied screws from the hardware list above. (Anchors included are 
designed for mounting on sheetrock.)

2.  Using the box as a template, mark with a pencil where the three pilot holes 

will be drilled.

3.  Using the appropriate drill bit size, drill the pilot holes (Note that if drilling 

into wood or metal a specialized drill bit may be needed.)  

See Drill Diagram.

4.  For sheetrock; use a hammer to gently tap the anchors into the pilot holes.
5.  Place the box up to the pilot holes or anchors and insert the screws 

accordingly.

Wiring the Device to the Timer

NOTE - For outdoor installation use rain tight or wet location conduit hubs that 
comply with requirements of UL 514B (standard for fittings for conduit and 
outlet boxes).

1.  Remove 2 screws retaining the interior cover panel and remove the panel.
2.  Refer to Figure 1 and wiring diagrams to determine appropriate placement 

of wires. It is the responsibility of the installer to ensure that all applicable 
National and Local code requirements are met. If you are unsure of these 
requirements, contact a licensed electrician immediately.

3.  GROUNDING: This enclosure is of plastic construction and does not require 

a ground connection. This enclosure does not provide grounding between
