BX Wiring Replaced

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.

Fire Hazard: If the hot wire touches the metal casing, the system can heat up and start a fire.·  
No Ground Wire: The ground wire in modern wiring better assures shock prevention.
Shock Hazard: Without a ground wire, the BX circuits pose a greater electrocution risk.·  
Loose Connections: Metal casing is meant to provide a ground path, but fails when connections loosen
‍Insulation Failure: Aged cloth and rubber insulation increases the risk of short circuits.·  
Overloaded Circuits: Not designed to meet the demands of today's electrical devices
Violates Code: Not compliant with 3-prong outlets and current electrical codes

BX wiring was often installed alongside knob-and-tube wiring and ungrounded Romex wire. In certain years (typically during the 1920s and early 1930s), electricians could choose from all three kinds of wiring. In some cases, electricians at that time stuck with one style of wiring throughout. But we more frequently see all three styles mixed together in one junction box.. You may be able to go into your basement and quickly identify all three types of wiring.

Multiple generations of wiring in one system increases complexity, troubleshooting difficulty, and safety concerns. The practice would not be permitted under today's NEC National Electrical Code.
