I keep hearing that if you leave old cables (i.e. 208v, 500mcm) alone in conduit they should last and last.
Varnished covered cables from 1929 may still look good and megger out OK but:
When will the next upgrade to the wiring occur?
Can you assume an owner will replace the cable before the next ninety years go by?
Is 180 year old wiring OK in anybody's mind?
I have read reports by Engineers and heard Architects repeat the same mantra of leaving old cables lie and still using these antiques.
Am I crazy to insist on replacing cables in excess of 50 years old?
Is there a better number?
Thank you in advance.
