ECN Forum Forums Code Related Discussion Canadian Electrical Code Topics Pig Tailing AL to Copper

I've used both methods of aluminum terminations (pigtails/COALR devices) COALR Devices are quick to use, however still not offered in DECORA. 63's (brown) are the maurettes I would use for CU/AL pigtailing. I have not heard of any problems with these methods. When performing this work at a house with aluminum wiring, usually I find evidence of burning/arcing in one or two splices.
