Does the NEC prevent a 240V, 20A receptacle being installed in a domestic kitchen? The receptacle would supply a 3kW cord- and plug-connected hot water kettle.

I do not know of any restrictions on 240 volt recptacles. I do not see anything wrong with installing the recptacle for your appliance.

Yup, the receptacle is allowed.

However, it may need GFI protection.

I think GFCI regulations apply only to 120V circuits.

GFI rules apply to 220v items also. Same as 120v rules. You may be able to get by if the outlet is single and dedicated to only one appliance

2002 NEC 210.8 (A) "All 125 volt single phase 15 and 20 amp recepts in locations specified in 1 through 8 shall have gf protection for personel" I see no requirement for gfci on this installation.

Still firmly attached to your British-style tea-making facilities, eh, Hutch? [Linked Image]

Wouldn't it just be easier (and cheaper) to get a 110-volt electric kettle?

I'm sure they sell them's just a small pot with a resistance coil to boil water, right?

NEC 210.8 requires all 125-volt, single-phase, 15- and 20-ampere receptacles installed to serve the kitchen countertop surfaces to be GFCI protected.

Paul, you hit the nail right on the head - it's all down to *power* and the fastest way to achieve phase transition. The highest rated 115V kettle I’ve come across here is 1500W with the majority on offer being only 1000W – I saw one rated at 750W! Morning tea is a must and time is short at that time of day. One cannot beat 3kW of grunt to raise 2 pints of cold water to boiling point in about a minute.

Guys, thanks for your replies. On the same vein I see that 210-6 (a) (2) restricts voltage at receptacles in dwelling units to no more than 120V if the cord and plug-connected loads are less than 1440 volt-amps (or ¼ hp). How does one satisfy the AHJ that this is the case (i.e. a 3kW kettle) – after all, once installed in a new bare house the occupant could plug any 240V device into it.
