This editorial will focus primarily on electrical inspector certification and recertification in the United States for the purpose of covering proposed changes that will affect the IAEI program in the US.
In this article, we will cover some of Canadian Electrical Code requirements for standby power and transfer switching.

The 1998 Canadian Electrical Code has made some more changes in the rules for underground conductor ampacities.
