Grouped Service Disconnects?

[Mike01]

Seprate service??

A discussion started between some co-workers the argument is:
Is taping a meter (residential) on the load side feeding a fused disconnect, or going underground to a garage mcb panelboard, considered a violation because the main disconnects are not grouped together, to me if the conductors are serving a seprate structure it is not a violation if it serves equipment in relation to the home (ex. air cond. Installed adjacent to the meter) would it be??

I believe Mike Whitt brought this up awile back and there was quite a lengthy discussion on it. I will try and find the post.

Here is the thread

A/C Service??

A/C Service??

Here is what it leads to in a existing residential home, they sometimes provide an a/c service as an ?interruptible service? this way a service upgrade to the panel can sometimes be avoided and it supposedly gives you a discounted rate on you?re a/c. however when this is done (the way I have seen it) they tap the load side of the meter feed another meter (line side) and all the associated controls, then the load side to a fused disc. Sw. located on the outside of the house to the a/c. so how does all this fit in? you now have a fused disc. Sw. for the a/c and another inside an mcb in your panelboard?? Is this then legal??

Mike if the service is tapped and both meters are on the same building then I would think you would have to group the disco.

 

[Mike01]

Hmm.

Hmm.

That was the opinion of the majority but when they do these services on existing residential homes they just provide a disc. Sw. on the outside, leaving the panelboad disc. Sw. as the mcb inside, it sounds like they should provide a disc. A wireway and tap those conductors.

 

[Dennis Alwon]

Yes, the least they should do is have a disco outside for the panel inside but then that would make the interior panel a sub panel and you would need to separate grounds and neutrals and perhaps change out the cable.

The fact is it is not legal as you state it.
