| If you can find power switches and receptacles made for
the aluminum wiring then use them. If you cannot find them, you have a few choices. Here is the one I have found easy to implement. PIGTAILING USING 3M "SCOTCHLOK" TWIST-ON CONNECTORS Buy some twist-on electrical spring connectors. Red and Grey are the most useful sizes for aluminum wire pigtailing of the #12 and #10 wires (15 and 20 amp circuits, respectively). Red connector can accommodate from two to five wires size 12 or 14 Red connector can accommodate from one to three wires size 10 Grey connector can accommodate from three to seven wires size 14 Grey connector can accommodate from two to six wires size 12 Grey connector can accommodate from two to four wires size 10 3M Scotchlok Red P/N 054007-20058 3M Scotchlok Grey P/N 054007-21346 The idea is to use the pigtails to extend the aluminum wires by adding a piece of solid copper wire then connect the copper wire to the standard power receptacle made for the copper wires. To comply with the electrical code, you have to use the proper connectors and coat the wires with the oxide inhibitor. Here is how: Apply Penetrox A (oxide inhibitor) to the wires Clean with the #240 grit "wet-or-dry" abrasive paper Coat the wires with the Penetrox A again Pretwist no more than three wires Cut off the ends Fill the connector with the Penetrox A Screw on the connector as far as it goes Wipe off excess of the Penetrox A |
| Where to buy? If you need just a few pigtails, buy them at the local
hardware store. If you plan to replace most or all (recommended) of the receptacles and light switches in your unit, buy a box of 50 or 100 connectors on the Internet. It will be cheaper. |
If you have more part information and would like to make it available, send it to webmaster@netnut.org and I will publish it.
