| TimFox:
To be fair, it's more difficult to touch the button contact ("live") than the threaded contact ("neutral") with the bulb removed. I'm more concerned about touching the thread while removing the bulb: that's why I prefer properly polarized connections, where only a few volts lie on the "neutral". |
| SL4P:
This thread has come to the realisation there is no safe or foolproof outlet design. Mostly thanks to ill-informed installers, designers or users. The most reliable safety solution is to use whatever combination of bare conductors you want, and liberal use of RCD/RCBO protection devices as close to the main isolator as possible. - or for those having ‘special needs’, a fixed wiring path from the main switchboard to the ‘point of use’. |

Or forbidden. --- End quote --- Could you share a picture of an insulated, safe-to-touch E27 lamp socket? I don't think I have ever seen one. In the sockets I am familiar with, both contacts on the inside -- the one on the thread, and the one at the bottom -- can be touched when the bulb is unscrewed. But since both contacts can be touched anyway, connecting the socket via a polarized plug wouldn't make it much safer... ::) --- End quote --- The ones in 110v festoon lighting are about as safe as they get; the thread is plastic with only a small contact near the bottom, and if you're fool enough to stick your fingie between that and the centre contact, you only get 110v across the tip of your digit. |

You won't get the standards changed by ranting, so get used to them? :-// UK plugs best in the world? Looks like he was made by a maniac, or when circuit breakers didn't exist. Most Europe uses Shucko, we're just fine, we're not dying in thousands. Looks like chaos? Ask Japan, where Tokyo is the line dividing the country in 220V and 110V. I guess it's the reason they sell so many electronics! :-DD |
