Knob/Tube wiring

My brother has just moved into a 100+ year old house with old knob, tube wiring here in midtown Mobile and it doesn't appear brittle or anything of the sort. Also in the attic and walls there is zero insulation. What advice from you all who have experienced having this type of wiring can you give me for my brother such as electronics not to use, any wiring appearance that could signal trouble? Apparently the breaker box was updated in recent years as it previously had the screw in fuses (still has a gross of em in a box). thanks.

My advice: don't buy 100+ year old houses unless you have the money to pay a legit contractor to update them.

I bought some rental property a couple years ago with knob and tube and no insulation. The good thing about KnB is the hot and neutral are about a foot apart in the Attic and so never short out. I talked to an old guy I know that owns a bunch of rental property and knows his shite. He said it is OK to put insulation on top of KnT. In the end, I have been re wiring it. But I can do it myself.....although figuring out hot and neutral on KnT is a pain.....there isn't a black and white wire.....it's all dark brown. To pay someone to do it I may have chanced it. I did put radiant barrier on the rafters which did help a lot but not enough. I am 90% through the rewire
ETA: The KnT wire gauge is pretty hefty. So there is really no limit on electronics, etc other than if you keep tripping a breaker.....then take something off of it. KnT isnt usually grounded so definitely put a good power strip/ breaker between the wall plug and electronics. I do have some downstairs rentals that still have KnT and have never had any problems.

Sorry, my Electronic Engineering lexicon only goes as far back as 80 year old houses.

I live in a KT house. Never had an issue.

I was told that a main concern was arching between the wires.. that kinda got me going "huh?"

Was he able to get insurance on the house? Does the Insurer know about the K&T?
We sold my childhood home last year that had K&T. The Home inspector noted the K&T wiring and instructed the new buyer to check with his insurance carrier. No insurer would issue a policy on the house until the wiring was replaced. Fortunately, the new buyer was willing to split the cost of replacement.

I'm not westom, but what would constitute "good"? I know surge suppressors require a ground in order to function.

The only place that could happen is at the switch or plug in where they are close together. Even then, its rare that would happen. Best advice is don't change out a switch or plugin when you have to start messing with the wires. That's when the old wire insulation crumbles and you expose bare wires.
