Technical Support

Full technical support can be provided by you local branch, however over time we are hoping to build up this section of our website with the most frequently asked questions. We have started this section by providing you with some general technical information on some of our core products.

We can provide technical information on:

Cable - Ratings and connection factors
Conduit - Capacity tables
Trunking - Capacity tables
Conversion tables - Imperial to metric
Electrical Symbols
Emergency lighting - Latest levels
Fire alarms - Basic requirements

If our technical pages do not answer your questions please remember our team of technical experts who are available to help you with any technical query on a whole range of issues.

If we can help please email: technicaldesk@cef.co.uk

You can download PDF versions of our technical pages, but to do so you will need Adobe Acrobat Reader. To download it for free, click here.
