Tip: Safely Checking Unit Cabinets For Power

By Gary McCreadie

Through the years I have spoken to many techs in person and online.  I have noticed that a good number of them have been taught to use the back of their hand to slap a unit cabinet to ensure it has not become live.  A poor ground or lack of ground can cause a unit cabinet to become live if a problem exists within.  I understand where this thought comes from, if you reach for a live unit with your bare palm, there is potential for your hand to cease up and grab on and obviously your back hand can not grab.  However, this method is still unsafe.  Today, we have tools to safely check for power before touching unit externals.  Check out the video for more info and a quick demo.  Stay safe...
