ECN Forum Forums General Topics of the Trade General Discussion Area Heavy ups?

A customer in his 50's asked me if we do "heavy ups". I had heard this term used about 6 years ago and remebered someone telling me its another way of saying panel upgrade or service upgrade. Does anyone know where this term "heavy up" came from. Thank you.

my guess is it would be Heavy Duty Uninterupted Power Supply

It means to upgrade the service "Heavy it up" as in "Beef it up".
Apparently it is slang in the MD / D.C. area, as David Shapiro (the author who resides in that region) uses the term in his books and magazine articles.

Maybe old school like 120 to 220 volt changeovers, porky pull installations. These are a couple I have heard in the past from old timers

In the DC area it was an upgrade when I lived there (typically 100a to 200a).
