"mention US being 110v service voltage..."
M.
I agree, someone writing an article should be more accurate.
Referring to household voltage as110v has become so pervasive that it has become part of our permanent vernacular.
If asked for a voltage requirement (such as ordering an appliance), you are nearly always asked "110v or 220v?" instead of 120v, or 240v. Even by professionals.
What bugs me more is the misuse of words like "Ironic" in place of coincidence,
or "Issue" instead of problem. (....but then I digress)
Btw, it is not (or seldom) a "service voltage".
A "service" implies the supply conductors comming from the electrical utility.
