220 wiring, alluminum to copper??
helping my parents with a project, and will hire an electrician, but I want to understand.... house has alluminum wiring. They are replacing a wall oven/M-w single unit with 2 sepreate appliances. I need to add a new dediacted 110 for the MW, can I run new copper in the old panel? what is the solution? the oven is hard wired, can I join old 220 alluminum to new copper (using proper purple caps)? Thanks in advance
