Looks like the discussion is veering OFF the main issue raised--what the initiator meant, I think, was about the Qualifications of the HANDS-ON persons working--NOT the Head of dept.
Most often, in the hierarchy of an Organization, the Head of the Dept--call it O&M or Maintenance, etc--comes from one of the streams--Electrical, Mechanical, Civil, C&I. However, the primary persons who actually work hands-on will essentially HAVE to be qualified appropriately.
Coming to the main query of the initiator, the experience level of the person being referred to [who doesn't seem to be having any electrical qualifications] is not mentioned. I have known persons, by virtue of vast experience [typically >15/20 yrs] as an assistant to another qualified person in that function, but with little or bare minimum educational [NOT technical] qualifications, working in stand-alone/independent positions later on. But they rarely move above lower supervisory levels--since the topic was of Electrical, that would mean to the level of handling LT rather than any HT equipment.
