Kuhlman Electric™ specializes in replacing first-generation ungrounded BX. This early armored cable first appeared in the early 1900s. It relied on its metal jacket for grounding, and over time those connections loosen and fail. The original rubber-and-cloth insulation also becomes brittle and can crumble inside boxes. If your home still has ungrounded BX, hiring Kuhlman to replace it is a safety improvement that will protect your family and home.

BX became common through the 1920s–1940s. It is not the same as today’s code-compliant armored cable. Early BX had no dedicated ground wire and was often installed with two-prong outlets. Many homes still have this aging system hidden above ceilings and behind walls.

If you know your home has old ungrounded BX, now is the time to address it. Call Kuhlman Electric™ today and have us evaluate your wiring and bring your home into the modern era.

Kuhlman Electric™ spec replaces first-generation Ungrounded Romex wiring. This type of wire is found in many homes built in the 1940s, 50s, and early 60s. It's an early non-metallic cable that has only a hot and neutral conductor, with no dedicated ground wire to safely clear electrical faults.

Over time, the rubber insulation beneath the cloth jacket dries out, becomes brittle, and can crack or flake away. While this wiring was acceptable when installed, it does not meet modern grounding standards and limits safe use three-prong outlets or add new circuits.

The Kuhlman Electric™ team will carefully remove your aging ungrounded Romex cable and replaces it with modern, code-compliant wiring that includes a proper equipment grounding conductor. We take extra care to protect finished walls and ceilings, minimize disruption,
