ECN Forum Forums Code Related Discussion NEC & other Code issues 110.26 working clearances

Disconnects in drop ceilings...if max height is 6’6” in 110.26 where is exception to allow disconnect in T Grid? Seems like the working clearances are to protect you from grounding yourself while servicing equipment. Also the job I’m on they are pushing this exception (???) to the hill with plumbing pipes obstructing the 3 foot in front of disco, which is mounted at 9’ AFF.

Thanks,
