When connecting aluminum service conductors to a breaker panel do I need to use - RogerTib - 01-13-2020
On Square-D service panels, are the main lugs rated for aluminum wire? Or do I need to use an anti-oxidant compound? What about on Milbank outdoor meter bases?Aluminum to Aluminum they say you do not need an inhibitor. I have still aways used it as has every electrical contractor I have worked for for 30 years. Utility companies use it on all meter bases as well. The oxidation can still be persistent so I suggest you use it and torque them to the manufactures labeling. So many people over tighten the conductors and this is a major problem because aluminum is very soft it does have a torque guideline for each conductor size as well as the lug it is attached to.
