Transformer Vault Room Design for Commercial/Office Buildings
Transformer Vault Room Design for Commercial/Office Buildings
(OP)
Hi,
Need some guidance regarding the design of a transformer vault room (please see attached link for a copy of the plan). The vault room is beside the genset area but entrance for both is of a rool-up door type. Is there prohibition to use a roll-up door window, assuming everything is satisfied (from ventilation, etc.)? Will this violate some safety regulations?
Thanks
Arvin

Your roller door looks very close to the TFs you should consider the fire rating of the TF or, if not fire rated, the door.
There looks to be a pillar in front of one of the TFs also.
Looks like a pretty hard-core setup for an office building. 3-off containerised gensets?

Any negative implications if the transformer is near a pillar?
Yes, this is basically a building that will cater to business process outsourcing companies, that is why there is such a redundancy.

If this is subject to NEC, you may well be violating different sections of it by using a non-rated door. Check 450.21 on up through 450.48--you didn't say the type or size of transformers involved but those sections will help answer your questions.
The pillar itself isn't a problem but you'll want to be able to get the transformer back out once the installation is complete. As it is, it looks like the transformer on the left is blocked in by the other transformer and the column.
