Aluminum wiring to copper

[Mark E. Northrup]

hello everyone
My question is can a Aluminum main service wire coming into the main service panel be spliced to copper so it can reach the lugs. I inspected a house this week that had this in the main service box.
Thanks Mark

Do a search on the forum, there is very good information to start. You can also post a photo(s) and some members will take the time to comment.

You need a special lug that is for that application. Some of these lugs even require a special paste to prevent corrosion.

thanks jeff that was perfect. The application was not correct but i was not sure if you can pigtail on the main service lines at all from alum to copper.
