Disconnecting means

[infinity]

Ok I can see that where there is no foundation, empty land and building is going to be built but how can you do 2 in concrete with existing building already built?

You build a form around it and pour in the concrete. The purpose is to not have unprotected conductors running into the building installing a non-fused disconnect as previously mentioned will not solve that problem.

Does a non fused disconnect switch loacted first device on load end of utility meter qualify as service disconnecting means?

I'm confused. If you have space for a disco, why not just make it a fused disco and avoid the controversy?

See post #14, efelon already convinced OP to do that.

Is the disconnect rated as Suitable for Use as Service Equipment (SUSE)? Has to be marked as such.

Which NEC article says service disconnecting means Suitable for Use as Service Equipment?

It is in 230 part V or Vl, same area as all the other stuff we been discussing.

I think I found it then NEC 230.66.

If you have a nonfused disconnect after the meter you still are dealing with service conductors after the disconnect so you must have overcurrent protective device before or as near as possible to the point of entry.

I was wondering if NEC 2014 requires mechanical linkage between service fused disconnect near utility meter and main breaker in panel located inside not near point of entry of service conductor?

No, it would make no sense.

Main breaker in panel not even required. You have a main service OCPD in the fused disco. It is protecting the panel already.

Think about it.

Well main in breaker in panel is to protect the panel.

if you have a fused disco, you don't need a MB panel, just main lug.

edit: unless you needed to protect the panel per 408.36, but you should coordinate the panel rating with the fuses in the disco.

Panel is double protected. Fuses and breaker-twice. Overkill, not a problem, but waste of money.

Fuses protect feeder (from disco) and panel. A MLO panel would work. Think about it.....

Many times I can buy a main breaker panel with breakers (contractor pack) cheaper than a MLO panel. That's counting having to buy breakers separate for the MLO.

Single phase, for sure. Three phase, def not. Don't remember if OP said what this is.

My point was double protection not needed. Breaker is superfluous.

How about waste of resources?

If you have a fused disco it's already protected.

Am I the only one who gets a little disoriented every time I glance at Rob’s picture?

The black stripes seem to twist. Kinda cool really.
