Fair enough. I do think you are misinterpreting the specs of the switch, but it is not really a big deal. I find it interesting you call it a code issue and Wylie says otherwise. In any case, cheers. :beer:

The switch body is the same (HBLMITL), but the hp rating changes based on what receptacle is installed in the switch. So yes, the hp rating is "determined" but not necessarily "equal" to the receptacle rating. That is why they can have a switch/receptacle combination that has a higher HP rating...

Even if you look at single phase the hp rating of the switch (in that brochure) is *more* than the rating of the plug/receptacles it uses.

Here is something interesting: you can buy mechanical disconnects that incorporate standard NEMA plugs and receptacles, but which have higher hp ratings. For example, a switch rated at 5 hp that uses a standard L15-20 (3 hp rating). Or a switch rated at 10 hp that uses a standard L16-20 (5 hp...

So using a device outside the specifics of their UL listing is not a code violation? OK.

Yes, as I said, the hp rating for the arktite plugs is a bit higher than NEMA plugs. But my point is that this rating pertains specifically to when the plug is used as a motor disconnect. Hence the *much higher* hp ratings for the arktite plugs in situations where they are NOT to be used as a...

Maybe you can answer a question I asked in another thread that pertains to this. How do so many machinery manufacturers get away with selling 5 hp machines with NEMA plugs that are rated at 2 hp?

Here is one kind of reference: http://www.cooperindustries.com/content/dam/public/crousehinds/resources/catalog-sections/p_section.pdf The tables on page 14 ("Arktite Horsepower Ratings" etc.)show hp ratings for Arktite plugs and receptacles (I have it handy because I just bought this style...

That plug rating is when used as a motor disconnect.

That kind of generator subpanel is perfectly fine provided there is an interlock device that prevents both "generator supply" and "main" from being on at the same time. These devices are usually simple mechanical brackets supplied with the generator subpanel, but may also be available separately...

The main panel for the house is in a detached garage? That doesn't make any sense to me. How do all the circuits get to the house? Surely you must have a panel in the house somewhere too.

I have a 60 gallon compressor in one corner, the other has a large dust collector and filter housing. These are the back corners, which are the worst place to put things you will use or need access to often, hence why I put things there that never need to be moved and which don't need much if...

What is "adequate" is whatever is called for in the plans. Yes smaller nails can do a fine job if you use enough of them. If I was going to be doing any framing (which I might soon) then I would want to go with 3 1/2 .162 pneumatic nails. However, these are not super easy to find so I would...

Just unclog the drain and keep it maintained. Much easier than putting in a curb and you will have to do that anyway.

Well, fair enough, but I have never heard anyone say "4-wire" when referring to circuits with 2 hots, one neutral, one ground. These days it is assumed that there is an EGC in the circuit, so "wire" and "conductor" tend to mean the same thing. Plugs and receptacles are a bit different because...
