The appliance will operate normally without the ground wire because it is not a part of the conducting path which supplies electricity to the appliance.

What happens if you don’t have a ground?
If your outlets and electrical box are not properly grounded, appliances and electronics you are using could end up passing excess current through you, using your body as a means to complete the path to the negatively charged ground. In other words, you could be shocked or electrocuted.
Is it OK not to connect ground wire?
As long as one of the two are grounded, there shouldn’t be a problem. Code bodies and safety experts say to bond both the fixture and the box, because there’s no way for them to be sure that a fixture will properly bond during installation.

Is a ground wire necessary?
The ground wire is not strictly necessary for the operation of a device, but it is still an important feature. This wire is designed to provide a path for electrical current to travel if the normal paths aren’t available. This could be because the other paths are damaged, or there is too much electricity for them.
Can I ground my house?
You will need to install a residential grounding electrode (grounding rod). It is an 8-foot length of rod, driven into the ground outside the home and connected to the neutral side of the main panel with a copper cable. Its job is to channel electrical surges away from the home and into the ground.
What happens if ground wire touches metal?
If the ground wires touch the metal box the breaker pops and the ground wires spark. The main feed comes out of a ceiling light fixture box. The ceiling box is two wire BX. I’m using NM to feed the junction box.
How do you upgrade electrical in an old house?
6 Electrical Upgrades Your Old House May Need Have New Wiring Installed. Put in Additional Outlets. Install a New Electrical Panel. Add Outdoor Outlets. Install Home Automation. Set Up a Home Theater. 5 Electrical Additions to Consider for Your New Yoga Studio.
Do electrical outlets have to be grounded?
since 1962, U.S. electrical code has required all outlets to have a ground. When an error or surge occurs with grounding, the energy travels through the ground wire to the electrical panel. There, it will trip the circuit breaker or blow a fuse, thereby shutting down the circuit before damage (hopefully) occurs.
How do you rewire an old house?
Steps to Safely Rewiring Your House Do an “electrical inventory” Check out local codes and pull permits. Decide whether you want to run just electrical, or data, fire, and security as well. Use your list to create a detailed plan of action. Watch for existing infrastructure.
