Short answer
It depends on the range. Many full-size ranges call for a 40A or 50A double-pole breaker; compact units may need 30A. The breaker and wire are sized together from the appliance nameplate, the conductor type, the run length, and the code. There is no universal number.
This question gets a lot of confidently wrong answers online. The honest version is that it depends — and the appliance tells you, not a rule of thumb.
Start with the nameplate
Every range has a nameplate (and installation instructions) stating its electrical requirements. That is the authoritative source for the circuit it needs. A good electrician reads it first; so should you before assuming.
40A vs 50A — both are common
Many standard ranges are happy on a 40-amp circuit; larger or higher-output models call for 50. Neither is “more correct” — the right one is whatever the range specifies. Over-spec'ing to 50 “just in case” isn't automatically safer and can cost more.
The breaker protects the wire
This is the key safety idea: the breaker's rating must match the conductors' capacity. A 50-amp breaker belongs on wire rated to carry 50 amps. Putting a bigger breaker on smaller wire defeats the protection — the exact mistake behind many hidden hazards. That's why a circuit upgrade changes both together.
Why we won't name a single wire gauge
Wire sizing depends on the breaker rating, the conductor material and insulation temperature rating, how far the run is, and the current code. Those variables change the answer, so quoting one gauge for “every 50-amp range” would be irresponsible. An electrician calculates it for your situation.
When to call a licensed electrician
Sizing a circuit correctly — and matching the breaker to the wire — is a licensed electrician's job. The cost of getting it wrong is far higher than the cost of the work.
