2 Entering Arguments…The need for Continuity of Power Continuity of electrical power to emergency communications equipment is essential.The probability that conventional power sources will be disabled during, or in the aftermath of, an emergency event is high.A multitude of 12v DC electrical connectors are in use, but no standard exists.To ensure #1, a standardized 12v DC electrical connector must be adopted by emergency response units, including HAMs.
3 Introducing…the 12vDC Anderson Powerpole Connector Single connector for 15A to 45A.Three contact options allowing use of #10 to #20 gauge wire.Low voltage drop (< 0.02 volts).Inexpensive (approx. $1 ea. retail)Exceeds the current rating of the wire (based on max temp rise).Self-cleaning contacts can be disconnected while energized.Keyed, but genderless connector reduces required parts inventory.No soldering required!

7 Powerpole Connector Assembly Procedure Strip 5/16 inch of insulation from wire and insert into the contact barrel.Crimp the contact using one of several commercially-available crimping tools (a lineman’s pliers will NOT work).Insert the contact into the connector housing until it clicks into place.STANDARD ORIENTATIONAlthough Powerpole’s are keyed (polarized) it is still possible to create a dangerous condition if two different sets of connectors are cross-wired. This can be preventedby following the standard orientation for the red (+) and black (-) housings, as shown above. This convention has been adopted by the manufacturers of all Powerpole accessories (e.g. RigRunners).
8 Powerpole Connector Assembly Procedure 123The “best” crimping tool is the West Mountain PWRcrimp, but it is somewhat expensive at $50. Alternative crimping tools such as the Gardner Bender GS88 or the Harbor Freight are available for less than $10. These latter tools will distort the barrel of the contact slightly during crimping which will interfere with the installation of the contact in the housing. This can be corrected by rotating the contact 90 degrees and gently using the crimping die to eliminate the out-of-round condition.
9 NO Incorrect Crimping Technique Regardless of the crimping tool used, the seam in the barrel of the contact must be against the rounded side of the tool’s die.
17 Closing ThoughtsThe 30A Powerpole is an ideal connector for 12vDC power connections.The housings mate together through molded dovetails. A roll pin is provided to lock the housings together into a two-wire connector. I prefer to use superglue on the housing dovetail as the roll pin can fall out (into your radio).Buy twice as many contacts as you will need for your project – crimping takes some skill if you’re cheap like me and are using one of the $10 crimp tools.Make lots of short jumper cables to other connector types (e.g. ring, spade, OEM T-type). They’re perfect for your emergency “jump-kit”.Think carefully before cutting the OEM connector off of your Yaesu Mark V and trying to install a set of Powerpoles. A jumper cable may be a safer choice.Keep your housings, contacts, zip wire, and crimping tool in your jump kit. This way, you can make field repairs or even construct new cables on the spot.Always, always, always follow the standard orientation diagram!
