Looking for help wiring an induction range.

I currently have a 1964 Frigidaire Cooktop, with a 30 amp breaker. The wiring looks to be 8 guage solid copper, but I can't verify because the wire is not marked anywhere. I will include pictures below. The breaker has the two hot, red and black connected to the breaker, and the white to the ground lug. The basement has been finished in my home, and I don't think a new run will be an easy option, as the wire runs perpendicular to the floor joists. The wire run is 50'.

My new induction range needs 50 amp service, so I'll likely have an electrician look at what I have, but I'm looking for advise on what gauge wire I have based on pictures, and sample wire from the electrician at work. He gave me samples of 8 and 10 gauge, but it's braided.

See sample photo's. I think I have #8 wire.

 

For 50amps you need #6. You will need to run new cable.

 

Welcome to the forums.

From what I see.... that looks like #10 wire on a two pole 30a breaker. That would make sense.
That white neutral wires looks like #12 (one size smaller)

You should actually be using #6-3 w/gr. wiring on a 50amp breaker.



As always.....late to the party..
