"Normal" butt splices as opposed to the COPALUM splices that require a special tool.
OK, so currently my Al mitigation plan is:
- Use Scotchlok spring nuts according to the instructions in alreduce.htm (scrape, no-alox, pre-twist) wherever solid aluminum mates to solid copper
- Use Alumiconn e.g. on fixtures with stranded copper or where space is an issue
- Replace any 14AWG aluminum wire
- Replace any 20A breakers on 12AWG aluminum circuits with 15A breakers
- On switches and outlets, replace with new CO/ALR devices
- Pigtail to copper for GFCI outlets in baths, kitchen, laundry, or similarly install GFCI breakers if I can find them for my panel
- Have an electrician check the connections at high voltage appliances and the service drop
- Keep my eye out for the feasibility of series fault AFCIs as they become available
