When installing a small tankless water heater under pedstal type lavatory is ground fault protection required by code. the tankless is 230 volt cord and plug connected.

I don't see anything in Article 422 either.

Do not forget to check the installation instructions, there may or may not be provisions for GFCI protection located there.

I've managed to spot a GFCI requirement in the instructions for most of the whole-house type on-demand water heaters, such as Rinnai. The point of use one's, like eEmax, don't seem to have that requirement.

The ones that require 50 plus amp, 240 volt circuits?

No, natural gas or propane, such as the Rinnai one I used as an example. They typically take a 120 volt circuit that draws something like .7 of an amp.

Takagi, Noritz and Bosch are three other common brands
