Customer Questions & Answers

What is the largest Mini-Split System that this special wire can be used on? and meet current codes?

It is only a 14 gauge wire and that seems small for larger mini-splits. just asking for clarification. 12,500 btu heat pump or 18,000
Asked by: Joe2020
The ampacity of 14 gauge wire is 20 amps as a starting point, but the NEC requires that 14 gauge never be used in a branch circuit with an overcurrent device (breaker or fuse) allowing more than 15 amps. Also, the wire must be de-rated if there are more than 3 simultaneously current carrying conductors. An additional derating is required if the ambient temperature is greater than standard. Derating may also be needed for a wet environment and if multiple cables are run closely together in certain cases. Note that if only 3 of the 4 wires can be energized at one time, no derating is needed for over 3 conductors, but the other factors may apply. With only the over-3 conductor de-rating applying, the ampacity will still be over 15 amps. If any of the other deratings apply, the allowed current may fall below 15 amps. These rules are all spelled out in the NEC and there are tables for calculating the effects of these factors, but the rules are complex and will require significant study. It may be easier to consult with a pro. (The AHJ will likely have a limited willingness to help design a compliant implementation.)

Is this 14-4 plus ground? are there 4 conductors plus a ground?

Asked by: Mike
Southwire's response notwithstanding, 14-4 ALWAYS means four current carrying conductors. What Southwire described in their response to this question would be 14-3 cable. I cannot account for this disconnect; maybe they are wrong, or maybe the product description is wrong. MC cable is always required to supply a ground conductor, but there are multiple ways allowed to do this. The most common way is via a separate green-insulated copper conductor.

Use with LG mini Split?

Has anyone successfully used this with an LG mini split system? I wired 1 ton single zone using 20 feet of this wire. The indoor air handler does not respond (as it there's no communication taking place between outdoor and indoor). I have voltage/connectivity.

We were able to complete our Christmas lighting extravaganza with the use of the 50 ft 14-4 electrical cable. Since the cable is water tight, the cable was buried underground for overall safety considerations. The cable is then snaked up our tree to benefit the lights. We used the black electrical wire for constant power meanwhile the red wire is controlled by a day/night sensor.
