Installing a 200amp disconnect

[beck]

what are requirement on hang a 200 amp disconnect.
should it be on strut from floor to ceiling? when it is not a permanent structural wall.

The only Code requirement is "securely fastened in place".
Way too many variables and methods to dictate one method.

You would have to be a little more specific...? Where are you putting it if there is no permanent walls around, and what will it be for?

On the other hand If you put it on strut supported from ceiling to floor you really can't go wrong as long as you have proper clearances.

Beat me:

300.11 Securing and Supporting.
(A) Secured in Place. Raceways, cable assemblies, boxes,
cabinets, and fittings shall be securely fastened in place.

Thanks Cantor,
The switch is been used for a air handler, and yes, I have proper clearance. The reason I ask, I don't think it would not be a proper to install on a structure made of sheet metal. Was not sure what the code requirements were on this.
I think the right way to go on this is strut from floor to ceiling.

Mounting directly to AHU is common practice.

What I done in the past is install strut with floor attachments and use the AHU as backing to prevent sway, that way you do need to run the strut
all the way to the ceiling.


Just some input,

Yes, I am in agreement with you. If the Equipment (assuming the sheet metal is ductwork or part of the HVAC equipment) needs changing out or maintenance in the future the disconnect could interfere with it.

Might be a good practice but I do not know that it is required by any code. Certainly not the NEC.

No..no code requirement that I am aware of either. I would just hate to remove something I just installed on another trades equipment because he has to modify, change order, service etc.

Hate doing something twice and only getting paid once.
