I'm aware that aluminum branch wiring has got a bad rep because of bad connection and the possibility of those bad connections causing fireswould AFCI's be a good defense against those bad connections if placed on aluminum receptacle/lighting branch circuits? I also heard about load testing circuitsWhat is that process all about and how is it done typically? Thank you for your input.
To clarify some errors in an answer - A GFCI has absolutely nothing to do with a ground wireIt ONLY senses a specific small current differential between the hot and neutral wiring on the circuit it is installedSide note - A GFCI outlet is a great way to help safety with older circuits that have no actual ground with the hot and neutral wiring in older homesIt will trip off when that current differential is achieved by some one or something causing current to flow from the hot wire side - to somewhere other than the associated neutral in that circuitIt is common to see GFCI being misunderstood as to how it worksIt is simply tagged with no ground stickers to indicate that condition, when used on a circuit with no groundThe stickers are usually included in the packageIf at all possible, it would be a good move to rewire to copperI know I would feel better once it was changed over.
