| 872608 | 2010-04-04 09:44:00 | IIRC it goes up when it rings, something like 72v. Not sure, but even 'on hook' voltage makes some sparks. | ubergeek85 (131) | ||
| 872609 | 2010-04-04 21:40:00 | Be careful though, they are live wires, seen a few sparks fly from phone cables before. You will receive a shock but it won't be fatal - there are more amps than volts. There is 50vDC for speech and 80vAC for ringing. Nothing a big boy can't handle.:thumbs: |

| 872611 | 2010-04-04 22:14:00 | Stay with your idea of a phone extension. Unfortunately, due to Murphy's Law of broadband connections, one of these days you'll need to talk to your ISP about a fault and it's almost essential to have telephone, modem/router, PC, monitor, power switch etc all within reach to allow you to answer their questions and try their suggestions. Thats what I want, everything together, however currently both phone jacks are at the other end of the house, and I have a 10 or 20 meter phone extension cable wending its way round the house to this room where i have a splitter on this end of it for the phone and the modem. I will have a look to see if I have 2 wire or 3 wire later today |

| 872612 | 2010-04-05 00:04:00 | Thought it was the amps that kill you .. :D Very true. It is a combination of amps and volts that do the damage, which is why you receive a good kick. Nevertheless, the amperage is not lethal. I used to work for The Firm and I've had many a shock which is most probably why the brain is a bit muddled, but nothing lethal. The thickness of the wiring tells you that there cannot be too many amps flowing so you should be safe. |

| 872613 | 2010-04-05 03:04:00 | There's some seriously bad (and unsafe) advice in this thread. It is amps that kill, not volts, but it is volts and load resistance that determine the amps that flow in you. Stand in the ocean and relatively few volts are needed to kill. Have wet hands and get a hand to hand shock and you can be killed by a very small current. I've had 20,000+ volt shocks from inside a TV set and all I did was jump and say ouch, but I've had low voltage AC shocks in conditions that made me sit down and breathe deeply for a few minutes while I got over the fright. Under the right (wrong?) conditions (grounding and heart) phone line ringing voltage can kill. Cheers Billy 8-{) |

The thickness of the wiring tells you that there cannot be too many amps flowing so you should be safe. .4mm copper wire will quite happily carry more than 3 times the current to electrocute you and fuses around 20 Amps. You can't assume that the only source of power on a telephone cable comes from Telco equipment. |
