    heavy duty shelf brackets

    Having a need to rearrange some of my electrical panels and mount my RPCs (rotary phase converters) I needed to make some substantial shelf brackets to lock into the E tracks on the walls of my machine shop van.
    they are made out of 3" channel with a 1/2" tab welded on them

    yeah, anyone dumb enough to go near one of my electrical panels while I am working on them deserve what they get. Electricity won't reach out and bite you, well High voltage will even from some distance away. but even that if you adhere to the 1 hand rule by never touching more than a single conductor and make sure you are not grounded your chances of getting stung are lessened. I don't work inside of live high voltage panels unless an absolute necessity. Once had to change out a couple of breakers in a 4100v panel and could not have it offline due to some critical equipment it supplied. Even with all my properly insulated and inspected PPE, tripple gloves and all that I was still very wary and aware of the dangers. Had a coworker standing about fifteen feet away from me holding on to a rope lanyard attached to my safety harness to yank me away in case of an accident. even if you are only mildly grounded 120v will shock you 240v will let you know it means business 460v will stop your autonomous body functions 4100v will burn off anything that comes in contact with it if you are well grounded and in wet conditions all of the above can be instantly deadly. Know this, it is not just the voltage that kills, it is the amperage passing through your body in the wrong place, {" A current of as little as 0.007 amps (7mA) across the heart for three seconds is enough to kill. 0.1 amps (100mA) passing through the body will almost certainly be fatal. However, the current involved in an electric shock is determined by the voltage and the resistance of the circuit."}

    Yep. Wired whole houses from beginning to end. One hand. And if I have to work live it is very carefully and again, one handed.
