SPLICING RECOMMENDATIONS |
| |
Wire splices are the weak link of any electrical
circuit. It is especially important to make
proper joints in irrigation systems because
the joints are exposed to wet and damp
environments that can cause corrosion of
the copper conductor and premature failure.
Here are Paige Electric's recommendations:
- For direct burial, above ground, or in
valve box installations: Model DBR/Y-6 as
manufactured by the 3M Company (Paige
specification P7364D)
- For installation above ground or in
valve boxes: Models 316IR or MGC as
manufactured by the 3M Company (Paige
specification P7365D), or Silicone-filled wire
nuts as manufactured by IDEAL Industries
(Paige specification P7372D)
