Running the wire and installing the box technically requires an
electrician.  The customer sets this up before our guys come on site.
Installing the transformer is pretty well a "no brainer" although an
Electrical "C" ticket (limited license) is often listed as a
requirement.  We pull permits on all our jobs, so they're done right (no
exceptions).
