Problems with the EMC requirements in BS7671

New requirements on Electromagnetic Compatibility (EMC) were been added to the 17th Edition [1], and have been in force since January 2012.

The new Clause 332.1 added some requirements that go beyond those in the EMC Regulations [2] and could increase that cost of some equipment, and the new Clause 444 does not provide sufficient practical guidance.

This brief article discusses these issues, and shows where to find well-proven practical guidance.
