Geo
Appliance. Utilization equipment, generally other than in-dustrial, that is normally built in standardized sizes or types and is installed or connected as a unit to perform one or more functions such as clothes washing, air conditioning, food mixing, deep frying, and so forth.
I realize this maybe a stretch, but could this allow residential boilers and furnaces to be cord cap connected,for use with portable stand by generators.

422.12 and 422.12 seems to suggest they are appliances.
But 422.16(A) places some limits on the use of cords.
A receptacle (not to be confused with an outlet in general) will only require GFCI is it is 15 or 20.I have been in contact with a code instructor and he feels it would be OK as long as it meets mfg.requirements,most of the mfg. Spec's I have checked on spec a disconnect at the equipment and proper circuit ampacity,the only draw back he stated was that normally boilers are installed in a basement and the outlet would require GFCI protection,not sure if that would be a good idea for a boiler.

Where (5) is unfinished basements.Dwelling Units. All 125-volt, single-phase, 15- and 20-ampere receptacles installed in the locations specified in 21O.S(A)(I) through (10) shall have ground-fault circuit-interrupter protection for personnel.

Did you take the minute to read 422.16(A)?
Again the appliance in question likely is not intended to be cord and plug connected, and would rarely meet conditions that allow for cord and plug connection. You could install a transfer switch, possible a simple three way switch is acceptable for this purpose unless it needs to be rated as transfer equipment, they do make small transfer switches that fit device boxes that are much more expensive if you must go that route. You maybe could then supply one side with normal power, the other side with a cord and cap - or if that isn't acceptable a "power inlet".I have been in contact with a code instructor and he feels it would be OK as long as it meets mfg.requirements,most of the mfg.
