Top 2008 Code Changes
Article 522 Control Systems for
Permanent Amusement Attractions
By Mike Holt
A new Article was added to address control systems used
for permanent amusement attractions. It was created because theme parks
bring together a unique combination of rides, show elements,
transportation, theaters, other facilities, live shows, and new
technologies.
The new Article covers the installation of control circuit power
sources and control circuit conductors for electrical equipment, in or
on all structures that are an integral part of a permanent amusement
attraction. The Article is divided into three parts:
- Part I. General
- Part II. Control Circuits
- Part III. Control Circuit Wiring Methods
