You can do anything you want (unless it's getting inspected), because it's
your house, and very few people will care if you burn it down.
What you are SUPPOSED to do, is install one 30amp breaker and one 40amp
breaker. Then run two separate lines to each appliance. It's ok to use the
existing wire for one of the circuits. You can probably use the same box for
both wires, but every box has a maximum capacity, mostly for heat build up
purposes.

I'm replacing my range with a separate cooktop and oven. The range is
on a 60 amp 240V circuit.

The new appliances have the following electrical requirements:
Oven: 30 Ampere, 208/240 Volts.
Cooktop: 40 Ampere, 208/240 Volts.

Also the manufacturer recommends a time-delay fuse or circuit breaker
and a separate circuit for each.

Can I use the existing 60 amp circuit for both?

If I need to get two circuits in there, can they share the same
neutral?

Both appliances will be connected wire-to-wire (no plugs). Can I use
the same box for both of them?

Thanks,
Matt
P.S. I'm getting conflicting answers and a wide range of quotes from
electricians, so I wanted to get a better idea.
