    Common trip breakers

    Wrong. A handle tie when installed either a legal tie or a 1/8 toggle bolt through the handle (NOT APPROVED, though illegal handle ties are illegal because they are not tested to operate under any condition) will result in opening of both CBs with a trip (fault) on one of the conductors.

    Buzz Noise from Breaker

    GOOD ADVICE in addition the poster should know that molded case circuit breakers trip between 6 to 10 times their rating. A 30 amp CB can trip on instantaneous current at 180-300 amps. A motor load starting current can approach this level and the CB (as noted by others) may be close to tripping...

    Monitoring power consumption?

    While I did not look at the posted site, monitoring KWHR on a residential service requires 2-Current sensors or current transformers, there are digital meters from EMON that do KWHR and actual KW in use simultaneously.

    MPM: 1st few residential electricians are going to 'KNOW IT ALL", nothing against them but you just can't learn "It all" doing residential. 2nd there are quite a few studies (check WSSC's web page) on AC currents and effects on water piping. To date there has be no data connection the two...

    Bonding ground rod to water pipe to nuetral bus

    It is possible for the water piping system between houses to carry current as this path is in parallel with the neutral conductor (as noted above), this current can be yours, your neighbor or neighbors. If the current is significant it could be the result of neutral connections issues in one or...
