The lengths not in bold meet the requirements for individual conductors or jacketed cable in free air, in water and in conduit. These lengths only meet the NEC ampacity requirements for individual conductors (not jacketed) in free air or water, not in conduit. On those tables, there are five squares that show lengths in bold. For example, 14-gauge, 75-degree-C pump cable is suitable for use with a 1-horsepower, 230-volt motor up to 250 feet from the service entrance. These tables list the maximum number of feet of each size cable you can run from the service entrance to the motor for each horsepower motor, based on a maximum 5% voltage drop. The Franklin Electric 'AIM Manual' features cable-sizing tables. If something happens to a customer that could remotely traced back to your installation, you stand to lose everything. For your own sake, don’t even think of installing a submersible pump without grounding it according to code. You no longer can use steel drop pipe as a grounding link according to code. This means running a green ground wire from the motor to the service entrance. In 1989, the NEC started requiring all submersible pump motors to be grounded to the service entrance. The compounding of PVC insulation and jacket material can be adjusted to make the final product very flexible, approaching that of rubber. Rubber has the most flexibility, but also highest price tag. The dielectric material used to insulate individual conductors, and in the jacket of heavy-duty flat jacketed pump cable, also has a lot to do with the flexibility of the finished product. If you find flexibility important - for instance, if you live in a cold climate where temperatures can makes cable difficult to work with - choose a product with finer stranding. You can buy size 10 pump cable with as few as 19 strands from some manufacturers, and as many as 49 strands from others.

The finer the stranding, the more flexible the cable. “Stranding” describes the individual copper strands that make up the conductors that, in turn, make up the pump cable. Submersible pump cable can be used between the wellhead and the control panel or disconnect, so long as it is run in conduit. Installers can often bury it in the ground, although some local codes require underground high-voltage wiring, even UF, to run in conduit. UF, on the other hand, is used between the wellhead and the pump control panel or disconnect. It is designed to safely carry electrical loads inside water wells so long as it is sized properly. Submersible pump cable runs between the wellhead and the pump in submersible applications, and is approved by UL (formerly Underwriters Laboratories) for underwater duty. There are two classifications of insulated multi-conductor cable used in submersible pump applications: submersible pump cable and underground feed cable, commonly known as UF. This article helps pump installers decide which type and size of pump cable to use.

The code contains general requirements regarding the type of cable to use when installing pumps, but it gives the installer some latitude as to the specific type of cable. Guidelines for electrical installations are contained in the National Electrical Code (NEC).
