Many of our customers have two-prong outlets. These outlets lack ground wires. What is the big deal of having no ground wire? Electricity takes the path of least resistance, and grounded wires are that path. When ungrounded electronics do not have a ground wire, you could become the ground.
Boston and Medfield are known for their historic homes. While these houses are charming and wonderful pieces of history, having historical wiring is more dangerous than quaint! If your house was built before ground wires were standard, or it was wired by an amateur electrician who took some shortcuts, you may have ungrounded outlets.
Even if your outlets have three prongs, that does not necessarily mean they are grounded! A mistake by the installer could mean that the ground plug is not connected. To make sure, a qualified electrician from Paul Macrina Electrical Contracting can use a circuit tester to verify your outlets are functioning properly.
