Laying separate lives: Ensuring electromagnetic compatibility is crucial to avoid interference from and to other electrical equipment
Article Abstract:
The Electromagnetic Compatibilty (EMC) Directive has been effective since January 1996, and contractors have to install electrical equipment that will not interfere with other equipment. Installing in a new building is straightforward as electromagnetic interference (emi) issues can be addressed at the design stage. Reducing the effects of emi is not so straightforward in existing installations, and achieving proper segregation is particularly difficult. With EMC considerations include earthing and bonding, types of cable, terminations, cable separations and environmental issues.

Now is the time to achieve electromagnetic compatibility
Article Abstract:
There is little guidance for electrical contractors on building panels which comply with electromagnetic compatibility (emc) legislation. Only a few products comply at present so it is important to ensure that the most suitable components are chosen for a particular control panel. Design of the circuit layout and the provision of earths can affect emc. The choice of filters depends on the circuit impedances while transient suppression devices can be combined to give the best emc. Enclosures also affect emc and should be carefully designed.

Be mod and go modular to build your own panels
Article Abstract:
All electrical contractors should be capable of building large control boards if modular systems are used. There are three types of modular enclosures. The most basic is the pre-assembled unit into which devices are fitted. More flexibility and larger sized boards can be made with self assembly enclosures which can be wall mounted or free standing. Modular enclosures save time and facilitate changes to the standard components as well as providing excellent access to all parts of the board.
