Attached is picture. Second meter from left on riser diagram feeds to panelboards and transformer. The electrical room on building floor plan is located in empty warehouse space and inside the warehouse part of space is office space for tenant. The panelboards and transformer shown outside office space which has diagonal are the same that are shown fed from second meter from left on riser diagram which fed office space electrical receptacles/lights/RTU.

The panelboards and transformer are outside of office space but are inside the warehouse so they are not totally outside. My question Should the panel and transformer be inside office space accessible to occupant? Is the panelboards and transformer location outside office but within warehouse per NEC 2014 Articles 225 or 230 or any other articles in NEC 2014?

I am sorry, but I am having a bit of trouble understanding your descption.

Here is what I can say from what I think you are asking.

Tenant access to OCPDs that serve that occupancy must comply with 240.40(B)(1) and (2).

All feeders past the main disconnecting means, where I assume you established your GES connection, that are inside the warehouse fall under article 215.
 
You see attached zoomed pictures of original posted picture with red circles they are Panel HV, RP and 30kVA transformer. Which are located outside open office tenant space but within empty warehouse so they are not outside the building/warehouse. Please ignore the square with diagonal it is not where office space ends. Office space ends by the toilet, office conference and break room sides.

My question is following: Do panel HV, RP and 30kVA transformer has to be accessible to occupants and inside the office space per any NEC 2014 articles? Or are they as shown on attached zoomed picture OK per NEC 2014, Article 225 or 230 or any other NEC 2014 article?

CQ,

I gave the section on tenant access to breakers and such. Did you read it?

The equipment serving a tenant space need not necessilarily be in the tenant space, often it is not.

225 is outside feeders, your feeders are inside, so........215-Feeders.

230 is services. You have said nothing about service equipment or conductors.

Not sure what else I can say.

Trying to help, but I am at a loss on what else you are seeking.
 
Neither 225 or 230 apply since you have a feeder to the transformer. The transformer/panel for the office area is in the warehouse space, I see no issue with that.

Therei is no 240.40 (B). 240.40 is for disconnecting means fuses nec 2014 handbook.

Warehouse is not part of office tenant space. Are they still ready accessible?

There is a door between the toilet and the break room, leading from the corridor into the warehouse space. If that door is locked by the owner, and if the office tenant does not have a key, so that the tenant is not allowed to enter the warehouse area in order to reset a tripped breaker on the panel that serves their office, then you have a violation. If the door is not locked, so that the tenant can walk into the warehouse to reach the panel, then it does not matter that the panel is not within the tenant's office space.

Is that what you were asking?

I can envision a potential problem arising sometime in the future. If the now-empty warehouse rents out more space to more tenants, that build-out process could render these panels inaccessible to the present tenant. But we do not have to do today's design to accommodate tomorrow's possible code violations.

In addition, I know of no requirement for tenant access to the transformer although in this case they would the same as the brekers.

True, but I can see one thing other we would need to know also.

Looks like a 480/277 panel feeds tranny to maybe a 208/120 panel.

Lighting and HVAC for tenant space could come from 480 panel.

Tenant would need access to 480 panel, but necessarily the tranny itself as you stated.

The entrance into the office is in the same space as the panel so I see no issue.

Not necessarily. I see a door to the outside at the bottom wall of the office. That might be the only door that the tenant is allowed to use.

If the panels and X-fmr feeding the tenant space is considered not readily accessible then either the ladies or the gentlemen are going to be out of luck also since one of the toilets is not readily accessible either.

I have another question the panelboard office space can be accessible from doors beside electrical room and door beside office. Is their anything in NEC 2014 regarding access to qualified individuals or will that make the panelboard not readily accessible?
