Why is a fire hazard
this is especially true for older neglected homes
Defective products affect not only the electrical trade, is all over
Old houses are not wired properly for today's loads "of appliances installed" and a few new houses too.
Time passes by, and we want all of the new appliances ok, What's wrong with that
We never bring more circuits in. We top into an old defective breaker, which allows power to flow without tripping because it is defective. Ok, what's the problem? Heat This heat will burn the breakers, the wire, and the house. that is why the insurance companies will get involved and ask to upgrade.
It is not a code, City, or the electrician's problem. The product is defective. This problem is between insurance and owners.
