Hi to all,
Danny, the home will undoubtedly have some older wiring styles, that have not been fully removed, you may see evidence of these is the basement or crawl space or in the attic. the quick was to check if they are still energized it to use a voltage tic this flashes and beeps when held against the conductors.

To find hidden building features with minimal invasiveness, a useful tool is a flexible fiberscope. These tools are not cheap, but they can be very worthwhile to own. The tool has a bright light source and an eyepiece in the body of the tool and a flexible fiber optic wand that delivers the light to the end of the wand and delivers the image back to the eyepiece. You use it by either slipping the wand through an existing crack along a electric box in to the wall cavity, or by drilling a small hole into the cavity. Spot checks near several boxes should tell you if any knob and tube was used.
The cost to own a fiberscope is around $300, but it can be a good investment.
