Your body has capacitance to ground so there will be a tiny current to ground with 120vac. You probably will not notice it.is it a risk to touch the case
Can you confirm what I've heard? That in the whole history of the Navy one person got electrocuted from a voltage as low as 47v?Naval shipboard electrical systems are ungrounded for battle readiness. The first ground fault will establish a ground reference and reduce motor operating efficiencies. If one of the remaining two legs faults to ground, the OCPD will open.
