For the option of fitting new cables in the future and EMC and G&B capabilities
At sea On land

The E-Spareblock has both EMC and G&B capabilities. Surplus room in each frame is filled out with solid E-Blocks. Using the spare blocks allows the option of fitting new cable in the future. The blocks are divided up in seven sizes, 5, 10, 15, 20, 30, 40 and 60 mm in square.

  • All dimensions are exactly the same for the standard MCT Brattberg components.
  • All Insert Blocks are marked with yellow marking (see instructions).

Grounding and Bonding

  • For grounding & bonding applications standard presswedge or endpacking is sufficient. 
  • Series RGS, RGB, RGG, and E-RGP These products are primarily intended for grounding and bonding of communication, instrument, power, braid or wire armored cables and copper pipes, up to max. 1 AWG.
  • Plugs and Wraps are only for use in Grounding and Bonding applications, not EMC
  • G&B datasheet

Correct and safe installations

To achieve the highest standard of safety, a cable or pipe transit must be installed correctly. As there are many different types of frame – which may be either welded, bolted or glued into position – and insert block, it is essential that installers known when to use the most appropriate installation method.

Called spares, they bear the designation A/0. The copper sheet forms contact between surrounding blocks and the frame. E-Blocks are referred to by their width, followed by the designation /0 (indicating solid). Thus a E-Block with a width and height of 15 mm is referred to as 15/0. The length of E-Blocks is always 60 mm.

Special and larger modules can be made to order.
