INSTALLATION GUIDE
Cable or Wire for Leak Detection Sensors
Leak Detection Sensor Cable is required when NOT run through rigid metal
conduit. Reference the Direct Burial Cable – Installation Manual (P/N 000-1041) for
further information. See below for Cable type and description:
Alpha 58411 (INCON P/N 600-0062)
Two conductor Cable for standard, 2 conductor
Leak Detection Sensors, 0.114” (2.9 mm) O.D.
Alpha 58113 (INCON P/N 600-0063)
Three conductor Cable for 3 conductor
Leak Detection Sensors, 0.128” (3.3 mm) O.D.
Leak Detection Sensor Wire can be used when enclosed within rigid metal
conduit — from the sensor to the Tank Sentinel console:
3
Type THHN, TFFN, or THWN, Black, White, and Red,
18 AWG (1.0 mm) minimum, 1500 feet max. wire run length
Wire required for the Tank Sentinel Console:
3
Power – 16 AWG (1.3 mm) to 12 AWG (2 mm) Max. – Black, White, and
Green.
1
Safety Ground – 12 AWG (2 mm) Green (2 may be required in some
locations).
A/R
Accessories – Type THHN, TFFN, or THWN, 18 AWG (1.0 mm) minimum.
Circuit Breaker
10 Amp — providing power only for the Tank Sentinel System!
Weatherproof Junction Boxes
Minimum 16 cubic inch (262 cubic cm) weatherproof junction box, cover, and cover
gasket for the manholes of: Liquid Level Probes and Leak Detection Sensors. See
chapter 5 about part numbers for 1/2” (12.7 mm) and 3/4” (19.1 mm) conduit
junction boxes and recommended manufacturers. Also use 3/4” (19.1 mm) to 1/2”
(12.7 mm) bushings for Probe/Sensor compression fittings. Also, see Chapter 5.
Use a weatherproof metal pull box for combining several circuits that will run into
the Tank Sentinel console through one or more conduits.
Use a separate weatherproof metal pull box to combine intrinsically safe (I.S.) liquid
level probe, and leak detection sensor wiring. DO NOT RUN OTHER NON-
INTRINSICALLY WIRING WITHIN THE I.S. PULL BOX! Run 1/2” (12.7 mm) or 3/4”
(19.1 mm) I.S. probe or sensor conduit from the manholes to the I.S. pull box, and
then run up to four, 1/2” (12.7 mm) or 3/4” (19.1 mm)conduit to the I.S. conduit
knockouts at the console.
