Franklin Water Pump Electrical Installation, Splicing Power Cable to Motor Leads, Repair

*CAUTION*

TAKE CARE TO PREVENT DAMAGE TO THE

CABLE DURING THE INSTALLATION.

F. ELECTRICAL INSTALLATION

When the cable is supplied on a reel, support the reel on a piece of pipe laid across a pair of sturdy saw horses. Locate the reel about 6 ft. from the well so that the cable unwinds from the top.

Prevent the cable from scraping on the well casing and avoid pinching the cable either in the pipe clamps or between the riser pipe and well casing.

SPLICING POWER CABLE TO MOTOR LEADS

A waterproof splice must be made to connect the power cable to the motor leads. An improperly made splice will become a service problem. There are different materials and methods that are used to make water tight

cable splices.

-Examples; by waterproof TAPE splice, RESIN CAST splice, or by HEAT SHRINK splice.

Method #1- Taped Splice

1- Remove 10 in. from the outer jackets of the jacketed cable, taking care not to damage the insulation of the individual conductors.

2- Trim the motor leads, so that the yellow wire is 3 in. shorter and the black wire is 3 in. longer than the red one. 3- Trim the wires of the cable so that the yellow wire is 3 in. longer and the black wire is 3 in. shorter that the red one. 4- Strip 1/2 in. of insulation from the end of each wire and scrape the metal clean and thoroughly clean the surface with solvent to insure a watertight splice.

5- Join like-colored wires with connectors and secure connectors with staking pliers. Pull on wires to make sure the wires are firmly crimped.

Fill each connector with solder to insure sound mechanical and electrical joints.

6- Bind each connection with approved self-bonding rubber tape, with the first layer extending atleast 1 in. over the insulation, and the second layer extending atleast 1 in. beyond the first. Apply two layers of plastic insulating tape, each extending 1 in. beyond the previous one. Bind the three connectors together with one lapyer of approved self-bonding rubber tape, and two layers of approved electrical tape, all extending over the outer sheath if a

Method #2- Resin Cast Splice

Prepare the 3-conductor power cable for splicing, insert a sharp knife blade between the cable jacket and lead insulation and strip the jacket back 2.6” from the end. Strip the cambric wrapping (if any) off of the conductors and strip back rubber insulation 5/8” from the end. Assemble the cable connectors and crimp them in place using a crimping tool.

Cut off motor leads to equal length. Clean off ends of the leads for about 12”, using a wet cloth with gasoline or solvent. Clean the end of the power cable also. Insert the three motor leads into corresponding holes in the bottom of the rubber casing and push them several inches

out the top. Crimp the motor leads into corresponding connectors, crimping the center one first. Bend the cables into line with the holes in the csing up until the connectors are inside the holes about 1/4” from the top.

Mix the resin as directed. Cut off a corner of the bag and squeeze all of the resin into the casing. With the roll of tape on hand, fold the bag, and tape the top of the bag snugly to the power cable until the resin runs out over the top.This will assure maximum coverage of the resin and minimize the size of the finished splice. When the resin is firm to the touch, the splice may be immersed for testing.

REPAIR

Although cuts and abrasions may not puncture the cable insulation, repair them in the following manner.

Use a solvent such as paint thinner or gasoline to clean the cable in the area of damage. Roughen the surface of the insulation with sandpaper and apply a coating

of rubber cement to the prepared surface and let dry for 1/2 hour. Cut off a length of 3/4” wide vinyl plastic electrical tape 1” longer than the cut or abrasion, and lay it smoothly over the damage. Start binding the cable with the same tape 1” in front of the damage lapping each wrap halfway over the previous one, until the binding extends 1” beyond the damage.

Wind the tape smoothly without wrinkles and avoid stretching it unduly. Add three more layers in a similar manner, each extending 1/2” beyond that beneath.

Apply a coating of rubber cement over the repair as an additional bond and to improve the resistance to

oil and solvents.
