    Default Protection at both ends of a circuit

    Just wondering how common this is or if this is something that isn't looked for. My brother is remodeling a house part of which is the kitchen. The double wall oven and the drop in cooktop require their circuits to be protected at both ends; the breaker in the panel and a fuse or breaker at the appliance. I kind of argued the stupidy of redundancy and even checked with an electrical engineer on the matter. Came down to the instructions specifically said to and for the cost of the appliances my brother wasn't going to take any chances with any possible warranty issues.

    Specifically:

    Observe all governing codes and local ordinances
    1. A 3-wire or 4-wire single phase 120/240 or 120/208
    Volt, 60 Hz AC only electrical supply is required on a
    separate circuit fused on both sides of the line (time-
    delay fuse or circuit breaker is recommended). DO
    NOT fuse neutral. Consideration must be given for a
    combination built-in oven and cooktop refer to unit
    serial plate of each.
    Table A
    Matt, that is both SIDES of the line, NOT both ENDS.
    This is a 240 volt circuit which has two "hots". This is standard wording for any installation.

    Matt,

    It does not say that.

    1. A 3-wire or 4-wire single phase 120/240 or 120/208
    Volt, 60 Hz AC only electrical supply is required on a
    separate circuit fused on both sides of the line (time-delay
    fuse or circuit breaker is recommended). DO
    NOT fuse neutral. Consideration must be given for a
    combination built-in oven and cooktop refer to unit
    serial plate of each.

    That is describing a 120/240 volt circuit which requires 'a breaker or fuse on both legs', i.e., as that says "fused on both sides of the line".

    Note that it specifically states "DO NOT fuse neutral". That pretty much gives it a way as to what they were saying. I acknowledge that it is poorly worded, but it is simply stating to use either a double pole breaker or fuses to protect each leg.

    It appears you are both right on that one. I mentioned your interpretation to my brother last night and it almost led to a fight. He's pretty hard headed and think he's right meanwhile he admits he never called electrolux for their "interpretation". I dropped it as it's been a few years since we traded punches and I'm currently dealing with a pinch siatica (sp) nerve. It was midly amusing though.

    I called electrolux this morning just to double check. They admitted that their wording could be little confusing. You two are right, the original electrician was right, the elec. engineer was right, my brother was wrong. I'll keep that one in my back pocket for now until I feel like needling him abit.

    Thanks,
    Matt
