ats clearences

[tom spruill]

I have a situation where 2 ats switches are across from each other and I have only 3 feet of space. Both ats's are 480 volt.
DO I need 3 1/2 feet as per 110.26 condition 2 ?

Yes you do. In fact, some might argue that you need 4 feet, per Condition 3. If you are called upon to work on this system, I would strongly suggest that you insist, indeed that you strongly insist, that the equipment be deenergized first. No job is worth risking your life, and working clearance is a real safety issue.

If this is a new construction I would say this would fall under condition 3 in Table 110.26(A)(1), requiring 4 ' of clearance.

If this is an existing building, I would say its condition 2, requiring 3-1/2'.
110.26(A)(1)(c)

Since you are asking this question I am assuming this is pretty tight quarters.

Depending on the physical size, one option would be to stack them , one on top of the other.
