Three feet horizontally and 8 feet vertically, most cases both the floor and the ceiling are less than 8 feet vertically from the rim. Occasionally the ceiling could be higher but unless you want a ladder to get into the tub the floor is usually nor more than 30 inches below the rim.
That's right we do it all the time with a mirror cover. But it has to be agreed upon beforehand as the mirror installer may charge for cutting the hole.
That is what I read it to say. Three feet horizontally and eight feet either up or down from that level.
I had someone one time that was complaining about strange feelings in lower legs while using the shower. Was non metallic tub, non metallic drain pipe at the tub, but metal drain fitting in the tub. Metallic water supply piping though. First thought was neutral to ground voltage, though it is hard to completely eliminate this and it was at levels you commonly find.
So if you dropped a toaster in the tub that was fiberglass, pvc drainage, pex water supply, would it trip the GFCI? I think not.
If more than 4-6 mA happens to flow then yes it is supposed to trip. If the item has an EGC in the supply cord, it probably will trip.
Mounting screw possibly driven into concealed wiring?
Whatever the source was was pretty high impedance because I am still alive.
Toasters, hair dryers, electric shavers, basically everything I can think of that would be used as a bathroom product does not have an EGC in the supply cord. And you do have potential. It doesn't have to be outside potential to shock or electrocute you. You have over 20 Amps of potential between the ungrounded conductor and the grounded conductor. And the GFCI can't tell the difference if you are the load or if the appliance is the load. All it knows is (current out / current returned) is it balanced within 4-6 mA? Since there is no alternate path, it has to balance. You become the load and there is over 20 Amps to travel through your body and the GFCI is asleep at the wheel
Before anyone corrects me I realize that potential is a function of voltage, not current
If you immerse a two wire appliance into tub that is insulated from any other potential, the only path for current is between the two supply conductors. Assuming there is no other path you still should be fine sitting in that tub. That doesn't mean the water can't take on potential and should something of differing potential be within your reach current can flow through you if you touch that item.
Yes but the fact it is a 20 amp circuit is likely why you bring up 20 amps, but it is the voltage potential that is the problem and the current that can possibly kill you is only in the milliamp ranges. A 20 amp inverse time breaker can let maybe 80-100 amps through for short time when motor starting is occurring. A class A GFCI is designed to respond to 4-6 mA difference within maybe 25 milliseconds regardless of what any branch circuit rating may be.
You're over looking that the code says "outside edge of the basin". If you measure from the left side wall over to the right side, which would be the outside, of the right basin, then that would be over 3'. So a receptacle on the left side of a vanity like your drawing would not cover the requirement for a receptacle to be within 3' from the OUTSIDE of the right basin.
I would say you are confusing "outside edge" with "far edge." It doesn't say "far edge." The outside edge of the basin, is just that--on, say, a self-rimming sink (or a vessel sink), you have an outside edge of the basin, and an inside edge of a basin. If the basin were filled to overflowing, the water would climb up the inside edge, until it reaches the top of the rim, and then flow down the outside edge of the basin
The left side of the left basin wouldn't be the "far" edge if the receptacle was on the left. I think the intent of the code is to not have a cord draped over a basin. So you either put a receptacle on each side or one in the center.
So if the receptacles can be located only on each side, how does that reduced the likelihood that a cord would not be draped over the basins?
