    Shared neutral heating
    Dear Sir
    I have several shared neutral circuits in my home. I am having a problem with the house outlets .I am using arc fault cicuit breakers and they get quite warm, I'd say about 95 degrees. Every week or so the breaker trips for no apparent reason. What I mean is no plugging in of extra appliences or equipment. The electrical load for this circuit is quite low basically three tvs and that is it. The circuit is a 15 amp circuit. Someone told me that it may be a current imbalance so I tried to run one TV one each pert of its own circuit but no improvement. When I replace the arc fault breakers with normal breakers no problem with tripping or heat. Please keep in mind that this is a two pole individual trip arc fault breaker specificicly for shared neutral application. Any help you can provide will be appreciated
    Thanks RR

    Arc fault breaker get warm. 95 degrees is not that hot to even be concerned.

    Nuisance tripping is part of having AFCI Breakers. Unfortunately this has not yet been perfected.
