This might seem like a pretty trivial question, but I have hesitated to do it. You know those little plastic thingys on the end of the cords that plug into the phone, phone outlets, etc. Well, I have a phone cord that is wired into the wall on one end, but the plug in end is broke and keeps pulling out. I have more plug ends and a gadget for putting them on, but I am afraid that the connected phone line might have electricity in it? Does anyone know about this?
