Electric Heating Systems; Branch Circuit Protection
by Shawn Gibbs
When designing an electric heating system for industrial processes, many factors must be addressed. These factors routinely include required power, location, ducting, air source, and controls, but circuit protection is often overlooked. Proper circuit protection is of utmost importance not only for safety but also to avoid costly downtime and repairs to the system. Electrical branch type and size of protection are important considerations when adding circuit protection to a heating system. Depending on the type of control employed, the speed of operation can also be a factor.
