2017 GROUND FAULT NIC

[ELKSPARKS]

HOWARD COUNTY MD IS ENFORCING THE 2017 CODE REQUIREMENT FOR EVERY RECEPTACLE 50A AND BELOW IN A RESIDENTIAL GARAGE TO BE GFCI PROTECTED. ALTHOUGH NOT IN THE NEC IT IS COVERED BY SOMETHING CALLED A "TNI". WHAT IS THIS? WHERE CAN I FIND IT .

Try, HOWARD COUNTY MD, .

Maybe they're reading the new requirement incorrectly or they have a local amendment.

BTW please turn off the CAPs lock.

I don't know what "TNI" is but is possible it basically means "local amendment" in one way or another. If so, then you probably must do it even though NEC alone doesn't require it.

If this amendment is true then it has not been posted to there website

Maybe a "TIA" (Tentative Interim Amendment) but I don't see one that would require the higher amperage receptacles in a dwelling unit garage to have GFCI protection.
