Here is a diagram on how we in the Southern Maryland area are building our power pole connectors.
One place some have ordered their connectors from is:   Cable Experts

   Housings should be mated according to the diagram above, viewing from the contact side (opposite the wire side), tongue down, hood up,
   RED on the LEFT, BLACK on the RIGHT. Use a 3/32-inch-diameter roll pin, 1/4 inch long, to keep the housings from sliding apart.

       Highly conductive silver-plated copper contacts allow minimal contact resistance at high currents. Self-wiping action on make and
       break keeps conducting surfaces clean. Contact dents keep connectors mated in high-vibration applications and provide quick-break,
       snap action upon disconnect.

       Non-corrosive stainless-steel leaf springs maintain constant contact pressure—ideal for frequent connections/disconnections and
       intermittent overloading. Durable, high impact-resistant, polycarbonate housing with UL94V-2 flammability ratings comes in many
       colors for circuit trace ability and coding.

       Identical connector halves are genderless—making assembly quick and easy and reducing the number of parts stocked. Molded-in
       dovetails allow for customized harness in a variety of configurations.

       The 30-ampere contacts are designed for 12-16 AWG wire. The contacts can be soldered or crimped to wires. A very expensive
       crimping tool is available from Anderson (we offer a very inexpensive alternative that does just as good a job). After a contact has
       been attached to a wire, it should be installed into the housing so that the housing spring mates with the underside of the contact.
       When you slide it completely in the housing you should hear a click when it passes the spring detent.

       To remove a contact from the housing, use Anderson insertion/extraction tool #111038G2. You may also substitute a very small
       blade (jewelers screwdriver or X-Acto knife) to lift up the front of the contact slightly over the detent and pull the contact out of
       the rear of the housing, allowing the contact to be removed.
