What percentage of campsites in a new recreational vehicle park must have a 50-ampere 120/240-volt supply installed?

In a new recreational vehicle park, the requirement for the percentage of campsites that must have a 50-ampere 120/240-volt supply installed is set to accommodate the needs of larger and more power-hungry RVs. A standard guideline in many areas, including Colorado, applies a minimum of 20 percent for adequate service provision. This ensures that a significant portion of the campsites can accommodate RVs that require higher electrical capacities for amenities like air conditioning and multiple appliances without overloading the system. Thus, by mandating 20 percent, it ensures that infrastructure can support modern recreational vehicles while promoting safety and convenience for users.
