While 60-amp fuse panels were made with at least one 240-volt wire for larger appliances, 30-amp fuse panels only provide 120-volt wiring, and they are inadequate for modern household electrical needs.
Only a certified electrician has the expertise necessary to run a ground wire from the outlet to the service panel and then properly ground it.
Many two prong outlets were installed in metal boxes.
It could also means that only part of your house’s electrical system is grounded.
You will want to test your outlets to find out whether they are grounded or not.
In comparison, newly constructed homes today are built with 200-amp circuit breakers (the service panels that replaced fuse boxes).
When there is too much energy running through a wire, the wire heats up, putting the house at risk for fire.To find out whether the metal housing is grounded, purchase a circuit tester.Insert one of the tester’s prongs into the hot slot (the shorter slot in the outlet).Upgrading your home’s electrical system can cost between 5 and 15 percent of your home’s value — a price tag many people cannot afford.With this in mind, regulators determined that homeowners with two prong outlets need not upgrade them.If the expense is a concern, consider having your electrician rewire select outlets into which you will plug larger or more sensitive electronic devices, such as a computer or game counsel.
