RoofSupport earthing kits are applied in accordance with NEN1010:2020 for equipotential bonding of PV material to the earthing system of the building or object. The earthing kits are available in various designs 6mm² and 16mm² UV-resistant wire based on different clamps and/or tinned copper cable lug. (See metal table) (In accordance with NEN1010:2020 provision 514.3.7, indication with color or coding is not required for metal construction parts or parts with conductors)
Use of earthing kits
The following guidelines are suggested for the correct application of the PV earthing kits:
- At each intersection of the PV and lightning installations, an equalization should be made.
- If the installations are parallel to each other, but within 50 cm, then the distance of the meshing is used as the distance in how often the installation should be equalized:
LPL1 (meshing 5×5 meters) connect the system every 5 meters.
LPL2 (meshing 10×10 meters) couple the system every 10 meters.
LPL3 (meshing 15×15 meters) you connect every 15 meters the system.
LPL4 (meshing 20×20 meters) you connect the system every 20 meters.
Here we do assume that the undercarriages of the PV system are interconnected. If this is not the case, this must be done or each section must be separately equalized at the lightning protection.
Note: equipotential bonding of the plant is not the same as earthing the plant. Earthing of the installation is done at an appropriate earthing point. The lightning protection is not.

PV earthing kit SR1 AB
Earthing kit for the potential equalization of RoofSupport wire tray system. The earthing clamp is mounted on the wire tray, whereby the tinned copper cable lug is used to mount the stainless steel self-tapping screw to the PV system. The serrated washer in combination with the self-tapping screw ensure proper potential equalization, despite any anodizing, painting or powder coating.
