Wiring a single family dwelling. Checked on the specs for the slide-in range. Amperage is 53 amps.
Would you'll wire with #4 SER Al. 50 amp breaker. 50 amp 4 wire receptacle. :?

Thanks
 
That doesn't sound correct, unless it is a hardwired unit. That fact that 53 amps exceeds the rating of the receptacle, I would say you can not use a 50 amp receptacle.
 
What is the KW listed on the nameplate? Take a look at table 220.55. You could get by with a 40 amp circuit.

You have to check the installation instructions also, The more restrictive will apply.
 
I doubt that a typical range designed for a dwelling requires more than a 50 amp circuit.
 
They are still in the trying to decide stage now. According to what I was able to find on the internet, the one is listed @ 53 amps & another is listed @ 40 amps. Sure like working with #6 SER a lot better!
 
My guess, if it is 53Amp it probably will be hardwired. Don't forget the local disconnect if it is hardwired.
 
I believe the 53 amps is when everything is on at the same time. Note 4 of Table 220.55 allows us to use the Table for the branch circuit load. Not sure if the nameplate overrides the table or not. I have not seen anything that states that unless the nameplate is considered the manufacturers instruction.

I suspect you may have to use the nameplate. This may be another case of the manufacturer wanting to cover their butts. I guess I can't blame them.
 
How many of you guys have inspectors that when inspecting a new home will look at nameplate on the range?

proper receptacle (50 amp 4 wire vs 3 wire) and proper overcurrent protection on the conductors used (40 or 50 amps depending on conductors used) is all I ever see being looked for. Some may be surprised how big of a range can be put on a 40 amp circuit and never trip a breaker. I can not recall ever having a service call for overload on a range circuit unless something was wrong. Table 220.55 sees the real world load conditions in this way, you can have up to a 12kW range and only need to figure it at 8kW for a single range installation, that is only 2/3 the capacity of the range. The notes say for over 12 kW to 27kW you only have to increase that value by 5%.
