SJE JB Plugger Installation Instructions

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 en­ closure will be at grade once back­ lled 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.

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.

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 O-ring 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. 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.

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 oat 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.

12. Connect the conductors from the
alarm oat switch to positions 3
and 4. Coil remaining cable into the
junction box.

13. Seal the 3/4” terminal adapter with a
conduit sealing compound.

14. Plug the piggy-back plug and pump
plug into the receptacle.

15. Secure the junction box cover using
the two preinstalled screws.

16. Turn on power.

17. Check the installation by manually
tipping the oats on the pump and
then the alarm oat.

18. Test the unit periodically to insure
proper operation.
