Anderson Powerpole Connectors: The Ham Radio Standard

Every power connection in my shack uses Anderson Powerpoles. Every portable kit, every go-bag, every radio. Ten years in and I've never had one fail in the field. There's a reason ARES groups nationwide mandated these things.

What Are Anderson Powerpoles?

Anderson Powerpole connectors are genderless, modular, color-coded DC power connectors. "Genderless" is the key feature — every connector mates with every other connector. No fumbling with male vs female. No adapters. Any piece of equipment plugs into any other piece of equipment or power source.

They're manufactured by Anderson Power Products (now part of Ideal Industries). The ones we use in ham radio are the PP15/PP30/PP45 series — the number indicates the amp rating.

For most ham radio applications, the PP15 and PP30 housings with 15 or 30-amp contacts handle everything from handhelds to HF transceivers. A PP30 with 30-amp contacts handles 600 watts of HF at 13.8V without breaking a sweat.

Why Hams Adopted Them

Before Powerpoles, ham DC power connections were chaos. Molex connectors on some rigs, barrel jacks on others, binding posts, Cinch-Jones, random automotive connectors, or just bare wire twisted into terminal strips.

Try deploying a dozen operators for an emergency activation when everyone has different power connectors. Not ideal.

In the early 2000s, ARES and RACES groups (particularly in the ARRL West Central Florida section, who deserve credit for pushing this hard) began standardizing on Powerpoles. The advantages were clear:

• Universal mating (any connector connects to any other)
• Easy field assembly without soldering
• Available in multiple current ratings sharing the same housing size
• Color coding for polarity identification
• Stackable for multi-voltage or multi-circuit setups
• Rated for thousands of mating cycles

By now, it's effectively the standard across US ham radio. Most new power supplies and accessories come Powerpole-ready, or at least offer it as an option.

The ARES Standard Configuration

This matters. If you assemble your Powerpoles differently from everyone else, they won't mate properly with other stations' equipment. The ARES/RACES standard:

• Red housing on the left, black housing on the right (when looking at the mating face with the tongue on top)
• Red = positive, black = negative
• Housings dovetailed together in a single row

Alternatively described: hold the connector so the flat side faces you and the locking tabs (the little nub/slot) are on top. Red is left, black is right.

I've seen people assemble these backwards. Everything works fine in their own shack because they made all their cables the same wrong way. Then they show up to a Field Day site and nothing connects to the group's power distribution. Big mistake.

Get it right from connector number one. Follow the standard.

What You Need for Assembly

Connectors:

• PP15/PP30/PP45 housings (red and black pairs)
• Contacts rated for your wire gauge (15A, 30A, or 45A)

Tools:

• Proper crimping tool (this matters enormously — more below)
• Wire strippers for your gauge
• Needle-nose pliers (for rolling back the contact retaining spring during insertion)

Wire:

• Appropriately sized for your current needs
• 12 AWG handles 30A and fits the 30A contacts perfectly
• 14 AWG for lower-current applications (HTs, accessories)
• 10 AWG for high-current runs (amplifiers, multiple radios off one feed)

Choosing the Right Crimping Tool

Here's the thing about Powerpoles: the connection is only as good as the crimp. A bad crimp causes resistance, heat, voltage drop, and eventually failure. I've seen crimps done with generic electrician's crimpers that looked fine but measured 0.3 ohms of resistance. At 20 amps that's 6 watts of heat in the connector.

Your options:

The right tool (recommended):

• Anderson's official crimp tool ( or the newer "TRI-CRIMP") — expensive ($40-80) but perfect crimps every time
• Powerwerx TRIcrimp — designed specifically for Powerpole contacts, $36-40, widely available from ham radio dealers
• West Mountain Radio's PWRcrimp — another purpose-built option, ~$40

Acceptable alternatives:

• Ratcheting crimp tool with appropriate die set (like the IWISS IWS-2412M)
• Must have the correct die profile for open-barrel contacts

Not recommended:

• Generic electrician's insulated-terminal crimpers
• Pliers (please don't)
• The "smash it with a hammer on an anvil" technique I've seen described in forums (no, really)

Spend the $36-40 on a proper tool. You'll use it for years. Every ham accumulates dozens to hundreds of Powerpole connections over time. My TRIcrimp has done probably 400+ crimps over eight years with zero failures.

Step-by-Step Assembly

Alright, let's build a connector pair.

Step 1: Strip the Wire

Strip approximately 3/8" (10mm) of insulation from the wire end. Too much exposed wire and it'll stick out the back of the contact. Too little and you won't get enough copper in the crimp barrel.

Step 2: Insert Wire into Contact

The contact has an open barrel at one end. Slide your stripped wire into the barrel so that:

• The insulation butts up against the barrel's edge (no bare wire visible between insulation and barrel)
• The bare wire fills the barrel without extending past it

Step 3: Crimp

Place the contact (with wire) into your crimp tool's correct die position. The TRIcrimp has three positions for 15A, 30A, and 45A contacts — use the right one.

Squeeze firmly until the ratchet releases (ratcheting tools) or until fully closed (non-ratcheting). One crimp. Done.

Give it a pull test. Grab the wire and tug hard. It shouldn't move at all. If it slides out, your strip length was wrong or you used the wrong die position. Cut it off and redo it. Don't try to salvage a bad crimp.

Step 4: Insert Contact into Housing

This is where people get frustrated the first time. The contact slides into the housing from the back (wire side). There's a small spring-loaded tab inside the housing that locks the contact in place.

• Orient the contact so the flat side aligns with the flat internal channel
• Push it in until it clicks
• Tug gently to confirm it's locked

If it won't seat: check orientation. There's only one correct rotation. If you're forcing it, something's wrong.

To remove a contact (mistakes happen): use a small flathead screwdriver or the extraction tool to depress the retaining spring, then push the contact out from the front.

Step 5: Dovetail the Housings

Each housing has a dovetail groove on one side and a tongue on the other. Slide red and black together following the ARES standard orientation (red left, black right, tongue on top).

They friction-fit together. For permanent assemblies, a tiny drop of super glue on the dovetail joint ensures they never separate. For field use where you might want to reconfigure, leave them friction-fit only.

Some people use the small roll pins that Anderson sells to lock housings together. Works great, adds permanence without glue.

Common Assembly Mistakes

After teaching Powerpole assembly at three Field Day events, I've seen every mistake possible:

Wire stripped too long: Bare copper sticks out the back of the housing. Potential short circuit. Fix: trim the wire flush before inserting contact.

Wrong contact size for wire gauge: 30A contacts with 18AWG wire = loose connection. The wire should fill the crimp barrel. Match your contacts to your wire gauge.

Housings assembled backwards: Red and black reversed, or tongue orientation wrong. Check against the standard before gluing or pinning.

Weak crimps: Usually from wrong tool or wrong die position. The crimp should be so tight you'd destroy the wire trying to pull it out. If you can pull the wire out with your fingers, it's wrong.

No strain relief: On cables that flex (portable operations), add heat-shrink or a cable tie near the connector. Repeated flexing will eventually work-harden and break the wire at the crimp point.

Power Distribution with Powerpoles

Once everything in your shack uses Powerpoles, you need a distribution method. Options:

RIGrunner (West Mountain Radio): Multiple Powerpole outlets from one input. The RIGrunner 4005 gives you 5 outlets with individual fusing. $60-80. The gold standard for shack distribution.

Homebrew fused distribution strip: A busbar in a box with individual fused Powerpole outputs. Many hams build these for $20-30 in parts. Plans all over QRZ forums.

Daisy-chain adapters: Y-cables with Powerpoles. Simple, cheap, but unfused (I don't recommend unfused distribution for anything drawing more than a few amps).

Portable power distribution: For go-kits and emergency deployments, a small distribution box with 4-6 Powerpole outputs lets multiple operators share a single battery or generator feed. Maxtrac makes nice compact ones.

Powerpoles for Specific Applications

HF Transceivers (20-23A draw): 12AWG wire, 30A contacts, PP30 housings. The factory power cable on most HF rigs is already sized appropriately — just terminate it with Powerpoles instead of whatever connector the manufacturer used.

VHF/UHF Mobile Radios (5-15A): 14AWG is fine, 30A contacts (because the housing size is standard). Some operators use 12AWG everywhere for consistency.

Handhelds and Low-Current Accessories: 16-18AWG, 15A contacts in PP15/PP30 housings. Works but the contact-to-wire fit is loose with 18AWG in 30A contacts. Use 15A contacts for small wire.

High-Current Applications (Amplifiers, 50A+): For legal-limit amplifiers drawing 50-80A on transmit, Powerpoles are NOT the answer. Their continuous rating doesn't cover this. Use Anderson SB50 or SB175 connectors for high-current applications. Or just use heavy-gauge bolted ring terminals. Powerpoles top out around 30A continuous in real-world ham shack conditions (the 45A rating assumes perfect crimps and ambient temperature).

Sourcing Connectors

Buying in bulk saves money. My favorite sources:

• Powerwerx: Huge selection, kits, tools, fast shipping. The 50-pair bags are the best per-unit price.
• Amazon: Fine for small quantities, but watch for counterfeits on cheap listings.
• HRO/DX Engineering: Stock them, sometimes pricier but reliable genuine Anderson.
• AliExpress: Genuine Anderson products aren't sold here. The knockoffs look identical but the housings are slightly off-spec and don't always mate cleanly with real ones. Avoid.

Buy genuine Anderson. The knockoffs cause problems at exactly the wrong moment (which, because this is ham radio, will be during an emergency deployment in the rain at 2 AM).

Final Thoughts

Standardizing on Powerpoles was one of the best collective decisions the ham radio community made. Buy a bag of 25 pairs, get the right crimp tool, spend a Saturday afternoon converting your shack. Your future self — especially the version that's deploying equipment at 5 AM for a served agency — will thank you.

73 and keep your connections tight.
