tankless water heater disconnect

[scwirenut]

would a gas (lp) whole house tankless water heater require a DS for the 120v igniter?

Cord and plug is good.

Oddly, even though these things take less than an amp, the manufacturer's instructions also want them GFCI protected. I know Rinnai and Noritz are that way.

Wouldn't this be permanent installation and a cord would be a violation?

Not that I haven't done it.

I've always done mine with an MC whip into a switch in a handy box. I have generally powered it from a basement receptacle circuit, which is normally GFCI protected by some means already.

Take a look at 422.31.

I have not connected any of the instaneous boilers or furnaces before, but the ones I have seen come with a cord and plug factory installed.

I saw this and wanted to share it ,..take a minuet fifty four and watch this

then decide if you would run a 30 amp circuit to a 15 amp rated receptacle.

Shower Head

Scary! A 30A OCPD feeding a 15A cord that plugs into a shower head. No way legal or UL. If the required bathroom receptacle is GFCI, that helps, but there is no guarantee. 406.8.b.c says no receptacles in shower stalls so this could be legal.
