Thank you for posting this. We ALL know this stuff, but it still don't hurt to review it every so often.

When I first started repairing radios, I used to buy Carbon-tet for cleaning tuners and control pots. You could buy it at any drug store. No one really knew how nasty, the stuff is. :thumbsdn: |
I suppose that with all mains electricity being 240 volts in the UK you would get twice the shock than at 120 volts that is used in USA. I know that some USA things run on 240 volts using a split phase = 120v-0-120v, so if you get a shock from any mains wire to earth/ground the maximum shock is 120 volts. However in UK if you get a shock from any mains wire to earth/ground it's 240 volts. All electric sockets & lamp-holders carry 240 volts. All appliance plugs have at least a 13 amp fuse in them, low power appliances(radio's, TV's, cable box's, table lamps) have lower amperage fuses e.g. 3 amp..

A very nice summary. Thanks for posting it.
The part about mercury acting as a "getter" and being the reason for the silvering on the inside of tube bulbs is dead wrong, though. The getter deposits are barium based. |

I get the impression that the Brits are more safety conscious about technology in general, maybe having 240V electric power is one of the reasons. I read somewhere that if you have a gas appliance, you have to get it inspected once a year or your gas gets shut-off also.

Thanks for sharing.
The UL should rewrite the rules that all AC items should have a fuse inline including CFL,LED lighting,Wall warts ,Kitchen Appliances and the list can go on. I'm tired seeing these fuseless crap devices killing people with fires . It would not hurt on the DC devices too with the powerful batteries. |

Most electrical fires are caused by misapplication of the items and most are items over ten years old. |

I have two fibre-optic Christmas trees, one has an AC motor driven color wheel and the other one doesn't. I grabbed the wrong, lower current wall-wart and used it on a higher current tree. Within a half hour the thermo-fuse did it's job, open primary. I found another at a thrift, for a buck. :thmbsp: |
You can find Beryllium oxide in home use tranzistor radios or that used only in big power stuff?
