Problems with K&T wiring

The largest problem with this style of wiring is that it is undersized for todays modern world and the wealth of appliances and 'plug in' accesories that are being used. The wire will tend to get hot and thereby degrade the insulation on the wire, that is if the squirels and mice haven't eaten it off already. Although a GFCI will work properly with K&T there still isn't a ground, which could cause shocks on some appliances (washers, driers, refriderators, dishwashers and garbage disposals are the worst). Although it's liable to cost several thousand to rewire a good sized B&B it is a lot cheaper than building a new one which eventually will happen, even if it's 50 years from now. I would at the very least run a new circuit to the room in question and wire to todays standards.
