I am upgrading my power to 200 amps. My electrician wants to use 4/0 aluminum wire (instead of copper wire) from the meter loop, to the service panel located inside my mobile home. Is aluminum a safe choice?

  • What's the distance? For large conductors that are professionally installed aluminum is a very sensible choice, as it costs much less than copper, even though it must be a larger size to carry the same current as copper. So long as it is properly terminated (which should be a given with a pro handling it), it's perfectly safe.

Yes. For service conductors aluminum is perfectly acceptable and typical in many/most places. AL conductors of today are not the same as they were 40 years ago, and the problems associated with AL were typically with smaller conductors, #12 & #10 solid.
