How to Install 252LR Deadbreak Elbow Connectors
This guide provides step-by-step instructions for the safe installation and connection of 252LR Deadbreak Elbow Connectors to UD jacketed or non-jacketed cables with concentric neutral wires or copper tape shielding.
Estimated time: 2h
Tools needed:
Wrench, Wire brush, Hot stick, Crimp tool, Wire strippers, Suitable sensing device (for voltage test)
Supplies needed:
Elbow Connector Housing, Compression Lug, Probe, Probe Contact, Lubricant, Hold-down Bail, No. 14 AWG / 2.5mm copper wire, Appropriate connector (for neutrals), Vinyl tape (if using drain wires), Conductive copper tape (if using copper tape shield kit), Cold shrink tube (if using sealing kits)
- Perform Pre-Installation Checks and Safety Review
Before starting, read the entire installation instructions. Inspect all parts for damage, proper rating, and compatibility. Ensure the elbow housing cable entrance size and compression lug size match the cable. Verify probe threads by hand-threading the probe into the compression lug. All apparatus must be de-energized during installation or removal. This product must be installed only by competent personnel trained in high voltage safety practices.
- Prepare Cable for Termination
Train the cable to ensure adequate slack for operation. Based on cable type (non-jacketed, jacketed concentric neutral, jacketed with drain wires, or jacketed copper tape shield), prepare the outer jacket, neutral wires, or copper tape shield as specified in the documentation. Ensure neutral wires are prepared for connection to tank ground. If using a sealing kit, slide the cold shrink tube onto the cable.
- Prepare Conductor and Insulation
Remove 2-1/8 inches (55mm) of shield and insulation from the cable end, cutting squarely without nicking the conductor. Wire brush bare aluminum conductors and immediately place the compression lug over the conductor, rotating to spread inhibitor. Align the lug's threaded hole with the bushing bore and crimp according to the lug's chart, rotating 180 degrees for successive crimps. Remove 6-7/8 inches (175mm) of insulation shield, beveling the insulation end 1/8 inch (5mm) maximum. Thoroughly clean the insulation.
- Assemble Elbow Housing and Probe
Clean the cable insulation and the inside of the elbow housing, then lubricate with the supplied lubricant. Slide the elbow connector onto the cable with a back-and-forth twisting motion, wiping off excess lubricant. Align the elbow with the compression lug's threaded hole. Thread the probe into the lug by hand, then tighten with a wrench until the wrench bends, ensuring not to cross-thread.
- Connect Concentric Neutrals
Insert one end of a separate No. 14 AWG (2.5mm) copper wire or equivalent through the grounding eye on the elbow and twist tightly. Twist all concentric neutral wires together and connect them to ground using an appropriate connector, ensuring adequate slack for elbow operation.
- Connect Elbow to Bushing Plug
Clean the receptacle portion of the elbow connector and the mating bushing, then lubricate with the supplied lubricant ONLY if both the transformer and elbow are known to be de-energized. Use a fully insulated hot stick to place the elbow onto the bushing. Do not operate by hand or separate if energized.
- Secure Elbow with Hold-Down Bail
Place the hold-down bail in the hold-down bracket. Pull the hold-down bail up over the crown of the elbow so the eyebolt is directly over the operating eye. Tighten the eyebolt by turning it clockwise until it seats securely in the locator. Adjust the nut on the eyebolt to act as a stop, preventing excessive force on the elbow.
- Perform Voltage Test (Optional)
If equipped with a capacitance test point, remove the test point cap with a hotstick, peeling it off at an angle. Use a suitable sensing device designed for capacitive test points to determine if the circuit is energized. Do not use conventional voltage measuring equipment. After testing, clean and lubricate the inside surface of the cap and replace it on the test point. Treat the elbow as energized until confirmed otherwise by multiple means.
