I don’t want to sound cruel, but I don’t think I want to go anywhere near anomalous1’s house. He keeps mentioning unsafe things like this that he’s done with electrical installations about which he’s totally unconcerned, while the things that he is concerned about are borderline impossible, like wires spontaneously breaking inside a conduit, or plugs sliding part way out of a socket and causing a fire.
I would complain to the landlord about the lack of a bathroom switch.
As to converting the socket to an outlet…I can’t find an adapter that converts the socket to a GFCI outlet but you could use a 2 part solution. You can use the socket adapter that converts the socket to a standard outlet - then you can add the adapter that converts the standard outlet to a GFCI outlet
There are GFCI extension cords. Plug one of those into the light socket adapter and you should be fine.
Unfortunately, that won’t work if the outlet does not have a ground and/or the circuit isn’t grounded to begin with.
If the service panel has GFCI breakers there is protection, GFCI outlets are safer because they have a quicker response time due to their proximity to the fault. The truth is, neither one may interrupt the power quick enough.
That said, it’s probably fine, your electric toothbrush charger and shaver are most like designed for “wet” conditions and do not have a ground anyway.
Good point. Considering the circumstances it’s likely not grounded.
I have a GFCI installed for the aquarium, and it indeed works in a two prong outlet house.
Yes, the GFCI measures the current flowing in the hot and the neutral wires and makes sure they are the same. If they are not, the current must be going somewhere - into a ground fault. No ground reference is needed.
As through my leg to a puddle of saltwater.
The one** Tripolar** linked to?
And now I recall, you have to mark a GFCI connected to a 2 wire system.
Yes, you must mark them as “No Equipment Ground”
Yes, it has to be labeled “NO EQUIPMENT GROUND”. I’ve found that GFCI’s that you buy at the hardware store always have such a sticker supplied with them for this application.
:dubious:
Let’s assume the average velocity factor for a given length of Romex is 65%. If the distance between the GFCI circuit breaker and the ground fault is 100 feet, it will only take 0.16 μs for the fault “signal” (the current imbalance) to get from the fault to the breaker. Are you saying 0.16 μs is significant? Heck, the max response time for a GFCI is 25 ms, which is 160,000X longer.
Gotta love the name…
DEFIANT!
Yeah, on further examination I’m not sure if they’re significantly quicker, although my inspector always asks"If you’re being electrocuted, where would you like the power to shunt off? Right here or 2 stories and 100 feet away?"
They do offer protection to a specific area and are much more convenient to test and reset which is recommended monthly. BTW, the statistics on GFCI outlets failure or not operating properly is shocking.
Hm, my first instinct is, as far away as possible. Shut off the whole building, or the whole neighborhood for all I care. Seems safer to shut off as much as possible. I guess your inspector is arguing the opposite, but I don’t really follow his reasoning.
The closer the GFCI is to you, the sooner it will shut off. Current travels near the speed of light, though. 65% mentioned upthread, 85% in an experiment we did in under graduate school.
They also taught us that 25 mA (25 thousandths of an Ampere) passing through your heart will kill you. Then they made us wear ground straps.:dubious:
Ground straps have a built-in 1MΩ series resistor.
And:
a) The difference between 6’ and 50’ is negligible - 60nS or so, which is many orders of magnitude faster then the GFCI reacts.
b) It’s not correct, anyway - the current starts flowing at the far end at exactly the same time as it does at the fault. It’s not like a traffic jam, more like a tube full of ball bearings, all touching.
At around 85% of C, which is pretty close to the same time. 
Huh? I agree with your second sentence, so what’s the point of your first sentence? Obviously a few hundred nanoseconds isn’t going to make any difference in the biological effect of the electricity.
