Is older home electrical rewiring necessary?
I am about to embark on a remodling project for my Mother’s house. The house was built in 1920, and has had some upgrades over the years.
The oldest wiring in the house terminates in two-prong outlets, and is copper wire; this is about 2/3 of the wiring in the home. An addtion done in the early 60’s was done with grounded 3-wire copper wire and is, approximately, the remaining 1/3 of th house’s wiring. Two years ago, we installed a new breaker panel.
I understand that wire ages, and that insulation becomes brittle over time, however, I am not aware of the guidlines as to when rewiring is necessary or mandated by code.
Are there any general guidelines as to when rewiring becomes recommended or necessary?
Thanks in advance!
