How many volts should come from home phone line? 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).
What voltage should be on a telephone line? The POTS phone line, with all phones on-hook, should measure around 48 volts DC. Taking a phone off-hook creates a DC signal path across the pair, which is detected as loop current back at the central office. This drops the voltage measured at the phone down to about 3 to 9 volts.
How do I test phone line voltage? Touch the “+” probe of the multimeter to the green and “-” probe to the red wires. If you have a second line, “+” to black and “-” to yellow. If you get a low DC voltage reading across a pair of wires (red-green or black-yellow), around 48v, you know that you are connected to the telephone company.
How much power does a phone line have? While telephone lines do have 48 volts of electricity running through them, it’s usually not enough to cause a shock, though it may affect a pacemaker. The electricity in a phone line does spike to around 90 volts when the phone rings, which can give a mild shock.
