Joshua describes a scenario that we call a “Knob & Tube Sandwich.” This happens when historic wiring is cleared from the basement ceiling or the attic, splicing the remainder of k**b and tube wiring, still active, to a new wire junction or splice. This is common in historic homes, so if you’re considering purchasing a home built before the 1960s, it’s a good idea to have a qualified electrical team take a deeper look at the existing historic wiring before you finalize your purchase. A k**b and tube remediation can be a costly, cumbersome undertaking and it’s best to understand what you’re getting yourself into. **bandtubewiring
