AWG) is fairly common in a lot of North America for modern residential development.
Installing an enclosure extender for unfinished surfaces, changing the enclosure with a bigger one or installing an extra adjacent enclosure may be carried out to extend the obtainable house. "Pig-tailing" which includes splicing a brief size of copper wire to the original aluminum wire, and then attaching the copper wire to the prevailing electrical device. The splice of the copper pigtail to the present aluminum wire can be completed with special crimp connectors, special miniature lug-type connectors, or approved twist-on connectors . Pig-tailing generally saves money and time, and is possible so long as the wiring itself isn't damaged.
The BC Safety Authority advises if the wiring is aluminum and was manufactured earlier than May 1977, the outer masking of the cable will be marked, no less than each 12 inches, with the word ALUMINUM, or an abbreviation, ALUM, or AL.
