    Assembly line manual lifting weight limit

    Thanks Kenat. It sounds like you're referring to the NIOSH equation that I mentioned. It is exactly what I need, except that it is limited to lifting while standing. I'm hoping that something similar exists for lifting while sitting - or at least some other guideline or method of calculating...

    I have a question about installing a GFCI on a machine which has a number of components, some of which run on 208V 3-phase and others on 120V single-phase. Is it possible/safe to install a GFCI at a single 208V 3-phase input to the machine and split the 120V loads off after the input using a...
