The inspection games are alway fun. In the Attic furnace game, you touched on not having water pipes in an uninsulated attic but also you can not have a humidifier either. Typically the IBC codes tend to call for a fully weatherstriped door for an insulated enclosure around an attic furnaces in cold climates.

I always try to use an armored metallic cable for pulled wires in existing construction even when NM-B wire is allowed by code.

First, because of its flexible nature it is easier to pull. Yes I know the connectors are a pain.

Secondly, a new pulled wire is not protected from future intrusion as is wire that was installed correctly in the original construction. How many times do we find hot wires when demolishing walls or ceiling with the use of a finely tuned sawsall blade? Boy I sure love it when I find conduit or armored cable.

For a narrow wall, I feel the tip is a good solution. Knocking off 1-2" of plaster keyway is probably not consequential but if the plaster was in poor shape to begin with I could see potential problems.

It also appears that the panel has used more than the 90% of capacity which is stipulated in most codes. Fun game and great tool to keep us sharp.

I also appreciate the estimating calculators. They are simpler and quicker than my other programs although they could be improved with a few more varibles such as regional labor costs or complexity.

Thanks FHB for becoming more useful to us contractors at the same time when your articles are sometimes more softmoric.
