Switchboards

Switchboards

Delivering exactly what you want with minimum effort.

A wealth of experience from our engineers most of whom have worked in the industry for many years, enables us to interpret your switchboard requirements with minimum information, saving you time, delivering exactly what you want with minimum effort.  

Expertise from ongoing testing to IEC 61439-2 allows our engineers to provide support to ensure your design will meet electrical consultants' specification.

Our switchboards are manufactured as fully welded sheet steel construction cubicles. All Forms Of Separation are covered to BS EN 61439-2 and our Design Verified busbar systems currently range from 400A to 4000A with Icw values from 30kA to 100kA. 

We have numerous Ingress Protection certificates to IEC 60529 ranging from IP31 to IP66.

Quality Assured

ISO certification is the outward evidence of a quality culture that runs throughout the business and is directly sponsored by the Managing Director

The quality of our design and build facilities allows for production of accurate component parts that are easily and efficiently assembled by & T's trained staff.

Unlike most sheet metal fabrication companies, our shop floor is maintained as a clean area to ensure a better working environment for staff and to encourage pride both in the company and in its products...

Our products have to be manufactured to comply with strict safety and performance standards, either internationally approved
