HEIGHT OF DISCONNECT

[fuseboy]

Customer would like me to lower 60A disconnect switches. Presently they are approximately 3FT., O.C., above grade. Is there a minimum height anyone is aware of that I must adhere to?

Not unless doing so would violate 110.26.

Why do they desire the change?

I wonder if ADA is an issue. Accesibility requirements specify minimum heights. They may or may not be applicable.

In some areas of coastal Florida, we have 100-year flood plane levels. In these areas, some electrical equipment cannot be installed below that point. Check with your building code and the AHJ.

DISCONNECTS ARE FOR OUTSIDE TRUCK DOCKS. MAY I BURY PVC T AND REDUCE TO SMALLER PVC ABOVEGROUND? CUSTOMER WISHES TO LOWER DISCONNECTS FOR AESTHETIC REASONS.

Customer wishes to lower disconnects for aesthetic reasons. Disconnects are outside for truck docks. May I bury pvc t's below grade and reduce above grade?
