Do I Need To Upgrade Main Service For A Garage Sub Panel

I recently got a call from an electrician who failed an inspection with some other inspector. He does non empathize why the inspector is requiring that the sub panel in the detached garage that he just put in must have a main disconnect when it is fed from an OCPD in the primary panel in the house. The inspector stated that there are more than 6 breakers in the panel and since it is a separate building, it gets treated as a service.

What am I missing here? Never heard of that. I don't see how 230 applies.

Oh yeah. The official is citing 225.33

I believe, nonetheless that this is already covered by the fact that the disconnect is present in the main panel of the house. I don't encounter where this applies for split structures.

Sounds as though 225.32, Exc. # ane applies (2008 NEC).

On another topic, accept you re-visted your OP on the "Gas Range In the

Kitchen" lately?

Some good input there! Was this some other one of your (infamous) grooming

topics?

A typical homeowner is non a qualified individual. Proof is that they had to hire an electrician to do the work. Exception 1 does not apply.

Looks equally though this is legit. I contacted three other inspectors and we were all schooled on this ane. Astonishing. Disconnect required.

Jeff.....why wouldn't 225.32 Ex i Apply at a SFD? The homeowner has control of his/her own disconnect(due south)...they can throw their own primary, why not the garage?

They are not qualified individuals. That is designed for a building maintained by qualified individuals such as a factory with a qualified, trained maintenance staff. Also, it needs to exist written

O.K., ..and then I'grand nonetheless chewing on this one. Since a principal disco is required in the detached

garage, is information technology because there are more than half-dozen breakers in the new panel? What if there

are only six breakers installed with blank spaces left in the panel? Also, is the

applicative code section in the IRC, Department E3501.v, 2006 IRC?

Thanks for ya`lls indulgence!

So If they are willing to hire a janitor with a tool chugalug they can say the home is managed by a qualified person?

I sympathise this is code and I will agree my nose and enforce information technology but the chance of a homeowner tripping the breaker on the load side of the feeder before he works on the wiring is exactly the same every bit him tripping it on the line side.

Personally I call up NFPA should remove the exception or extend it to single family unit dwellings.

There is no logical reason to have both rules. It is a lot more than likely that the commercial installation might be broken upwardly into separate tenants or that they lay off the "qualified person", than that a homeowner would non take the billow on the feeder bachelor to a qualified worker who needed to shut down the power.

After all, what is the purpose of the disconnect?

• #18

However, the panel must be suitable for service equipment. Not all main lug panels are suitable as service disconnects.

Please explain and a code reference would exist good also! I am asking considering, sometimes

when we ask for information, we beginning getting the telephone calls proverb that nosotros are being

obstructionistic, ..slowing up the permitting process, etc., etc.

How are we dumb `ol inspectors going to determine compliance on the console

you lot mentioned, or rather, how would you lot & others do it to achieve compliance?

Also, suppose the detached garage / bldg. is but ten ft. away from the chief ext. panel?

Nonetheless more than half dozen breakers installed.. Here, we DO occasionally become the discrete

structures that are located very close to the principal residence.

I assume we all take been talking near a feeder going to the other edifice with line side protection, not a tap.
