stacking capacators

Is stcking capacitors good or bad, on a compressor. For example: A compressor calls for a 75 mfd X 440 Vac capacitor. A 35 mfd x 440 vac + 40 mfd x 440 vac, wired in parallel. If one of these capacitors burnt out, the compressor may run, cause a severe burnout, instead of tripping a breaker? Any thoughts?

    I do it....

    ...only as a temporary fix if the proper size capacitor is not available. Wouldn't recommend it as a permanent repair.

    I dont see a problem,if one was to burn out it will most likely not start at all,and even if it did try the overload
    would properly take it out.

    I would make sure its 440 the 370 volt dont seem to hold up
    as wells as the 440,only and certain neighborhoods.

    Hmmm..I wonder why.
