Use of braided aluminum wires in 220 volt circuits

Topic:

Question: 

How typical is aluminium wiring to the circuit box and for all 220 volt appliances in homes and apartments? Is it considered fairly standard?

Answer: 

Hello John,

The use of braided aluminum lines for 220 Voltage lines and for transmission lines is very common and not a problem. As used in electrical panels, these wires should be coated at the point of connection with an anti-oxidant jell.

It is quite common to see the use of braided aluminum wires at the main wires coming into the panel, and the circuits for electric stoves, electric furnaces and other large 220 Volt equipment. In such applications it is quite unusual to see copper wires.

The problems with aluminum wires are with single strand 110 Volt wires and 220 Volt circuits. Such wiring was used for a relatively short period of time, should be corrected and is no longer is use.
