    Good point, Jack. The thought was in the back of my mind but never poked its way forward.

    Unlikely that both oven elements would be on at the same time. Most ovens are one or the other. Some ovens will turn them both on during a preheat cycle, but I haven't seen too many like that.

    I agree, If the breaker is tripping with only a couple of burners on, either it's a weak breaker or a bad element or switch.

I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.

    WHAT? No-lox is not required (unless your in Canada) and will not make any difference on the installation.

    Lloyd, you're right it's not required unless the wire is Aluminum AA 13000 series alloy, some types of USE, some overhead conductors or the connector shipped pre-filled with oxide inhibitor.

    I've seen bare AL crumble in wet/damp enviroments when it wasn't used.

    However, for decades now, I have rarely complied with the Code, I usually exceeded it and would not dream of terminating AL without using no-lox (or equal). But, that's just my opinion.

    Good Luck from Columbiana, Alabama
