Historic Detroit homes feature complex electrical evolutions. From original Knob & Tube to modern 200-amp upgrades, we decode the liability and cost of your home's power system.
Knob and Tube (K&T) was the standard from the 1880s to the 1940s. While functionally robust if undisturbed, it poses significant modern challenges.
K&T relies on open-air cooling. When modern insulation is blown into walls or attics, the wires cannot dissipate heat. This creates a high-probability fire hazard that many insurance companies will not cover.
A Detroit bungalow originally ran on 30-60 amps. Modern life requires 100-200 amps. We identify the exact capacity of your system.
Electrical remediation is a major capital expense (CapEx). We provide the data you need to budget for the modern standard.
"Upgrading from 60-amp fuses to a 200-amp breaker panel is the single fastest way to increase the insurability and resale value of a historic Detroit property."
Many standard insurers will refuse coverage or charge significantly higher premiums for active K&T. Most require a certified inspection and a plan for replacement within 30-90 days of purchase.
Look at the main breaker (usually the top large toggle). If it says '200', you have the modern standard. If there is no main breaker, or if you have a fuse box, you are likely at 60 or 100 amps.
