JB Plugger Junction Box Installation Instructions
This junction box provides a convenient location to connect all wiring required for a typical pumping station installation. The
junction box employs a receptacle to accept a 120 VAC or 230 VAC piggy-back plug and a pump plug.
The JB Plugger also features an easy-to-use terminal strip which can be used for connecting an alarm system in the junction
box.
The JB Plugger package ensures a liquid-tight seal and strain relief for the cable entering the junction box from the pumping
station.

INSTALLING THE JB PLUGGER JUNCTION BOX
1. Determine where the junction box will
be mounted on the riser. Mount the
junction box so the base of the enclosure will be at grade once backfilled as shown in Figure A.
NOTE: Bottom mounting to the 3/4”
terminal adapter may be preferred
in some instances as shown in
Figure B.
2. Access the riser by providing a 2 3/8”
access hole through the riser.
3. Place the 6” threaded conduit into the
terminal adapter that is already
installed in the junction box. Slip one
PVC washer over the conduit and
slide the conduit through the riser
wall as shown in Figure C.
4. After installation through the riser, slip
the 1/2” gasket and the second PVC
washer over the conduit. Determine if
the threads provided will be adequate
to tighten the assembly to the riser. If
threading is not adequate, remove the
assembly and shorten the conduit
until threading is adequate as shown
in Figure C. NOTE: The 1/2” gasket
should compress approximately
1/4” when lock nut is tightened.
5. Repeat steps 3 and 4 until desired
length is achieved. With PVC solvent,
weld the conduit into the terminal
adapter.
6. Mount the 3/4” terminal adapter to the
bottom of the junction box with the Oring and lock nut provided. A 1 1/16”
hole should be provided for the
adapter.
7. Mount the assembly through the riser
as described in steps 3 and 4. Using
the 2” lock nut, compress the gasket
and riser to secure the junction box.
8. Remove the backplate assembly from
the enclosure. Bring the wiring for the
pump power and alarm junction through
the 3/4” terminal adapter. Connect the
conductors for the pump to the terminal
block; connect N (neutral) to position 1,
and L1 (line) to position 2. Connect L2
to position 1 for 230 VAC installations.
NOTE: Overload protection, branch
circuit protection and main
disconnect provided by others.
Connect the conductors for the alarm
circuit to positions 3 and 4 as shown in
Figures C and D. Place the backplate
assembly back into the enclosure.
NOTE: If an alarm system is not
used, plug the third open position
in the cord seal with the PVC plug
provided.
9. Pass the piggy-back plug, pump plug
and alarm float cables through the 2”
conduit.
10. With the three position cord seal, route
the three cables through the seal,
leaving approximately 8” of cable to
work with. Insert the cord seal into the
panel terminal adapter and tighten the
hex nut until adequate strain relief is
achieved.
11. Gather all ground wires, including
grounding conductor on the cord seal,
and washer. Route and secure to
ground terminal as shown in Figures C
and D.
®
12. Connect the conductors from the
alarm float switch to positions 3 and 4.
Coil remaining cable into the junction
box as shown in Figures C and D.
13. Seal the 3/4” terminal adapter with a
conduit sealing compound.
14. Plug the piggy-back plug and pump
plug into the receptacle as shown in
Figure D.
15. Secure the junction box cover using
the two preinstalled screws.
16. Turn on power.
17. Check the installation by manually
tipping the floats on the pump and then
the alarm float.
18. Test the unit periodically to insure
proper operation.
