The UL book, General Information for Electrical Equipment - better known as the 'White Book' has listing information for ranges. In the 2003 version, on pages 219 and 221, it has ranges listed as Commercial and Household.

Can a UL listed commercial unit be installed in a residential (household) dwelling?

We are seeing more and more of the 'commercial' units installed in dwellings, is this permitted?

At first glance at your post my thought was well of course they can. But stopping before I typed and thinking, my only answer would be is there maybe a dual listing on the appliance in question? Giving it some leeway to be placed in either catogory. On the same level of questioning look at the listing from our favorite beverage maker in the office,(coffe pot)(they made me take the tapper out) most are listed as household use only. Is this a problem? My question to you is, do you see a problem using a "commercial appliance" in YOUR house.

I don't know about your house but mine does not have provisions for grease or large overhead hoods that you would find in a commercial kitchen. I wonder about using an appliance within its listing. Besides all that, most of that stuff is ugly. :D

The standards for residential appliances is higher than that for commercials appliances. This may seem to be counter-intuitive. Commercial appliances may be made heavier duty, but safeties and interlocking devices are required in residential, where commercial may depend for these by routine or outside devices. I suppose a master chef may want to have a commercial kitchen in his house, but if he did, he might run into problems with his building official. Variances may be required, or additional safeties installed.

For what it's worth I saw on This Old House that manufacturers are addressing this problem with household listed ranges that have that commercial look and size.

One of the problems they claimed was many commercial units are not listed for zero clearance to combustible construction.

This would prevent the normal practice of cabinets right against each side of the range.

But it is a DIY show so I make no guarantees. :D

That makes a lot of sense. Now I know why I was told by the building dept that the homeowner could not install the particular range they wanted. He argued with the Building dept saying his neighbor had one installed. The Building official said that it was not filed for :eek: so much for being neighborly.

I read recently in a publication from I believe UL that Ranges have to be listed and labeled for their use. residential units must say they are approved for residential use. the commercial units do not have as much insulation on the sides of the stove. I guess because of kids touching them. I will try and find where I read this. I think it was UL publication called code compliant
