dtontarski Posted March 16, 2007 Report Share Posted March 16, 2007 Yesterday I observed an oven and range - separate appliances – wall installed oven and counter top installed range wired with 8 AL protected by 30 AMP breakers. I generally see 6 AL on 40-50 AMP breakers for these appliances. As these were both installed flush – no manufacturer tags could be observed. Are there appliances out there that have 30 AMP requirements? Quote Link to comment Share on other sites More sharing options...

dtontarski Posted March 16, 2007 Author Report Share Posted March 16, 2007 Thanks Gary. I kind of answered my own question after submitting it by doing some online research. I guess without having the kw rating or access to the manufacture requirement I can't calculate this, but I do see that there are 30 AMP rated appliances out there.

PAbernathy Posted March 17, 2007 Report Share Posted March 17, 2007 Good thing to remember is you can always use a smaller size breaker on a larger size conductor...as long as it properly fits the terminal lugs and so on. However in this case the # 8 AL is rated for ( 60 degrees ) 30A so in this case the wire size is correct for the OCPD....Now as stated we would need to know the KW of the appliances to finish the calculation...the safety aspect is you know 30A can be handled on that 8 AL....so even if the feeder to the cooking appliances was under sized the OCPD will protect the conductors......which is about all you can go on right now without the other factors. Here is a nice calculator you can use if you ever find those values http://www.electrician2.com/calculators ... _REV1.html Quote Link to comment Share on other sites More sharing options...
