my take is that the disconnect still has to be fit for the intended use. So, if you regularly get 2 feet of snow, then wouldn't mounting it below 2' mean that it needs to be listed to be submerged ? lol

sure sure,, just get the sonor gimzo and find it but it will end up a frozen ice cube to break it open.

[ hear the beep,.... beep,..... beep,... ping,, ping,,ping,, ... found the target .....]


Merci, marc

We may be nuts but we also have heat pumps which work in the winter. :smile:

Not so much up here, the efficiency really starts dropping off when it gets cold, when they are installed they get electric back up.

Same here. With the high of cost of electricity in this area, you really wouldn't want to install anything that at some point used electricity for heat.

Is there a minimum requirement for the distance from a deck floor to the bottom of an AC Disconnect? I can't seem to find anything in the code book and I've been asked to keep it as low as possible, about 18" to the bottom from ground/deck floor. Any help would be appreciated...[/

May not be a violation but poor design.The problem I find most often is the electrician leaves the disconnect with a tail for the ac installer, who places the condensing unit in front of the disconnect violating the clear working space.

No i do not pass it the disconnect or the condensing unit must move.

2' all year or 2' in one storm? :smile:

Alongside a building you can never tell, after a blowing storm you will have grass showing in one spot and 6' away it might be 6' deep.

That was my thought. Wire it, check for voltage and close the cover. Now it's the AC guys' problem.

I really hope there are no apprentice that read what you said.I think we should be teaching them to be more concerned about the results of our work.

i agree with that one Bob,..


just like one winter storm i work few years back snow drift pile up at one spot and have to dig in almost 10 feet of snow drift to get in the breaker box and do the repairs [ just shoveling snow out took me about 2 1/2 hours ]

Merci, Marc

Your heat pumps work in the winter. Up North heat pumps work for about 4 days in the tail end of the Fall, then they switch over to the resistance elements for the remainder of the winter season.

Would that disconnect not have to likely require examination, adjusting, servicing, or maintenance while engerized.

Why not just shut power off to the disconnect? I do not see the need to work on a disconnect live... so I say 'ney' to working space requirements...

That wasn't the point. The point is that there is no code issue with this installation. We can come up with many other reasons not to do this type of work but those issues are outside the scope of the NEC. Personally I would never install anything so shoddy but the NEC doesn't feel that there is a problem with this installation or there would be a rule prohibiting it.


As far as apprentice training goes I agree. This photo should be in the "don't ever install anything like this file".
 
We can't even install electric heat here per the Energy Code. We use gas here. Not like we need it. It was a friggin 100 degrees one day last week.

I think that any disconnect is likely to be worked on while energized. So I always enforce 110.26

Please do not be offended. I agree with all you have said above.

Those are scary words to a New Englander. We might have riots here if we couldn't install electric heat. ;)

Only by developers and landlords.

I don't think anyone building their own house chooses electric.....cheap to install, very expensive to operate.

Most homeowner here choose gas, oil or up north, wood. :smile:

There you go Bob, taking my joke and getting all serious. Lighten up, will ya? :D If you live in New England and aren't well versed on heating systems, you must be from California. :D

So the disconnect for my garbabe disposal on the wall above the counter top is a violation??
