50 amp Stove circuit

[Part-Time]

the stove is rated at 50 amps
what size wire should be used ( 8/3 ? )
and what size outlet ( 30 Amp or 50 Amp ? )

Note 4.To Table 220.55

Branch-Circuit Load. It shall be permissible to calculate the branch-circuit load for one range in accordance with Table 220.55. The branchcircuit
load for one wall-mounted oven or one counter-mounted cooking unit shall be the nameplate rating of the appliance. The branch-circuit load
for a counter-mounted cooking unit and not more than two wall-mounted ovens, all supplied from a single branch circuit and located in the same
room, shall be calculated by adding the nameplate rating of the individual appliances and treating this total as equivalent to one range.

If you are using nm cable then 8/3 is not rated for 50 amps. You need to use 60C for nm

You can't use a 30 amp receptacle on a 50 amp circuit. What is the KW rating of the stove?

Isn't that just for calculating the total load on the dwelling?

Isn't that just for calculating the total load on the dwelling?

There is always some argument as to whether or not it is permitted to use that calculation to determine the size of the branch circuit.

 

[Little Bill]

Isn't that just for calculating the total load on the dwelling?

No, the rest of the notes in Table 220.55 are for the load but note 4 is permitted to be used for the branch circuit.

I have a client who's mother starts cooking by turning on all the burners and the oven to get everything warmed up. Well, one day after a couple years of abuse, the circuit breaker (Siemens) decided to not trip and to burn instead. What a mess. What I learned from that was it's much better to install conductors and breakers that will handle the load rather than smaller conductors and breakers that are the minimum acceptable, through deration, per the NEC. A small cost saving is not worth a fire.
