The approach you take will depend on your budget, your ability to access the walls, attic, and crawlspace and the level of demolition allowed.
This kind of remodeling is easier to do in a newly purchased home than a well lived-in one.
The best way to get this protection is to run that third wire, which is usually bare copper or wire with green insulation, from the outlet box back to the grounding bar in your main electrical panel.
In addition, even if you do get permission, you may find that you need to have a building inspection once you have finished to ensure that everything is working correctly. Place this to one side, it can be discarded as scrap later. You should take the mains wires, and cut off a small amount of the insulation. You can then attach the circuit breakers to the panel.
Once you have the permission, you can then start to work on upgrading your circuit breaker panel. Circuits which are under a lot of strain need to be divided into different parts.
“Aluminum wiring connections often loosen up over time,” says Greg Fletcher, a master electrician, educator, and author of several books on wiring.
“That can cause overheating and possibly fires at receptacles when appliances are plugged in to them.” An inspection can determine whether it’s safe to leave the wiring in place.
