Conduit Bending

Houses in America are wired in many different ways. Some are wired in NM (Non-metallic sheath), some in BX and still others are installed in conduit. Conduit provides many distinct advantages over NM (Romex) and BX (Metal Sheathed) wiring. Conduit protects the wire from damage, is bonded to ground throughout the circuit, and leaves you with the ability to come back later and add circuits
