Layout and Supports

Rules To Be Followed

You must follow these rules before installation:

• Check the layout plan and note the locations and type of supports required.

In designing supports, consider the following:

• Feasibility of fixed points in regard to horizontal run layouts.

• Fixing points on the structure and suitable accessories (plugs, etc.).

• Ensure sufficient carrying capacity of the supports. They should be able to support the weight of the cast resin busbar trunking system plus 90 kg, in accordance with IEC/EN 61439-6.

• The elements are comprised of three to five conductors in the following possible configurations: 3L, 3L + N, 3L + PE, 3L + PEN, and 3L + N + PE, as shown in the figure below.

• The conductors are insulated using cast epoxy resin - RAL 7030.

  • Degree of protection is IP68.

  • Insulation voltage: 1000 V.

• The weight of the elements depends on their rating. Nine ratings are available, from 800 to 5000 A for aluminum and from 1000 to 6300 A for copper conductors. The cross sectional areas and weights of the different ratings are shown in the table below.
