Are exposed telephone wires dangerous? It is true that the normal voltage in telephone wires, which provides the dial tone, is not dangerous. However, when the phone rings, a series of high voltage AC surges come through the lines, up to 100 volts, and this can be dangerous, especially to people with health conditions, pacemakers, etc.

How much current can telephone wire carry?
The POTS phone line, with all phones on-hook, should measure around 48 volts DC. This drops down to the 3 to 9 volt range when a telephone on the line goes off-hook. An off-hook telephone typically draws about 20 milliamps of DC current to operate, at a DC resistance around 180 ohms.
How many volts does a telephone line have?
The phone company sends this power directly to your house through a pair of dedicated wires that connect to your phone jack. When the phone is not in use, this is a constant DC signal (about 50-60 volts). When the phone rings, the signal is a 20 hertz AC signal (about 90 volts).
