Can Melaleuca cake machine use aluminum wire for power connection? In the newly rented store, the meters provided by the landlord are all connected by aluminum wires. Does it work? The aluminum wire is more than 6 square meters of copper. Hello! Aluminum wire can also be used, but the number of wires is larger than that of copper wire. That is to say, if the original copper wire of 4 square meters is replaced with aluminum wire, it will be 6 square meters, and if the original copper wire of 6 square meters is replaced with aluminum wire, it will be 10 square meter, and so on. If your 4500W electric baking pan is wired separately and not connected with other electrical appliances, it is enough to use six square aluminum wires, and the current carrying capacity of the six square aluminum wires is about 7500W when they are exposed.
