My question is: Our existing MCC with 480 volt buckets are currently 36” away from fixed hose connections. The NEC requires the clearance to be 42” from grounded surfaces. Since these were installed decades ago ( about 1972), are they grandfathered in and acceptable at 36” or do they need to be relocated to 42”. The hoses and spill pans are removable and are removed from the area when work is needed to be performed on the MCC.
