    The current draw of a bulb won't be the issue. Potentially larger issues are modifying your tool, which may affect warranty coverage, and not being able to have your saw light on unless the saw is...

    GFCI breakers are both overcurrent protection devices and differential current sensors. They make sure that all the current that goes out the hot wire comes back in the neutral wire. If any is...

    I have an enormous pair of Channel-lock pliers that often get used as a Crescent wrench, a hammer, an oil filter remover, and a home invasion deterrent.

    I agree - the cost of a large box is almost exactly the same as a smaller one - not sure why anyone would put in a 20 or 30 slot box other than a perception of "overkill".

    I'm guessing he means no "doublers" - a one slot dual breaker providing 2 120V circuits. Certainly double pole breakers are legal, and required for many things.

    +1 to what Joe said. Venting outside in a residential area isn't a good idea, probably at least as much from a noise standpoint as from the appearance of dust. Up here in the frozen northland...

    I have 19 Lithonia 2-bulb T8 troffers and 9 Lithonia 2-bulb surface mounts running almost 3 years now with zero problems in my shop and garage. You must have gotten cheap ballasts or a bad batch.

    Correct.
    Also correct provided that you have 4 wires - two hots, a neutral, and a ground. This is a NEMA 14-series plug/receptacle. The NEMA 14-30 and 14-50 are commonly used for this purpose.
