![]() ![]() Now I’m not saying all this to scare anyone, as these are pretty rare situations. To further demonstrate this, he got a temp light bulb and socket, and touched the wires to the frames and the bulb lit up!! I’ll never forget that. Sure enough, when we got there my father took his electrical meter and measured the voltage between the frame of the fridge and range and got 120 volts. The tenants claimed that when they touched the fridge and range at the same time (they were side by side) they got a shock. What is the chance of that happening? I remember when I was an apprentice my father got a call to house in Somerville. ![]() If you had the same exact situation (issue within fridge, hot touching ground within the appliance) but the circuit powering the fridge was GROUNDED, the circuit breaker would trip instead, preventing a potentially hazardous situation. Or if you touched a water source (sink) or standing on a concrete floor (basement) amongst other possibilities. Yes, it would have live potential, that if someone touched it while touching another appliance that has a ground, you would get a shock. The frame of the fridge would now be LIVE. A good way to think about it is like this – Imagine you have a refrigerator that has a metal frame/body plugged into an ungrounded (2 prong) outlet with one of those 2 to 3 prong adapters (you know the ones!), and within that refrigerator the “hot” wire is touching the ground wire or frame of the fridge. Wondering what is ungrounded romex and why should I be concerned with it? To understand the issue with ungrounded romex, we first need to understand what the ground wire does? (Note that the name ungrounded romex implies it has no ground) The ground wire is there for personal safety, it’s that simple. ![]()
