4-hole inspection connection, wire-bedding B for up to 40mm (aluminum) /AL/ AH03054

### Lightning protection system inspection joint

This inspection joint, made of aluminum, is used to connect the lightning protection wire to the sheet metal. It allows for resistance to ground measurement without the need to disconnect the wires, which is crucial for regular control and maintaining the efficiency of the surge protection system. It provides a reliable connection and easy access to the control point, facilitating inspection and maintenance of the installation.

The joint is designed for wires with a diameter of 8-10 mm and sheet metal with a width of up to 40 mm. Mounting is done with four M8x16 stainless steel screws, which guarantees durability and corrosion resistance. The aluminum construction provides lightness and good electrical conductivity.

Construction and application

The joint was designed with ease of installation and use in mind. Four holes allow for a secure connection of the lightning protection wire to the sheet metal, and the use of stainless steel screws ensures resistance to weather conditions and long-term operation. It is ideal for use in lightning protection boxes or manholes, where it provides easy access to the control point. Mounting at a height of about 1 meter from the ground facilitates inspection and protects against mechanical damage.

AH Hardt inspection joints are an integral part of surge protection systems, providing the ability to verify the continuity of the grounding circuit. This allows installers to quickly and effectively assess the condition of the installation, and end users to be sure of its proper operation.

Certificates and compliance with standards

The AH Hardt product has a SEP - BBJ class H certificate, confirming its ability to withstand lightning current impulses with a current of up to 100kA. It has been tested in accordance with PN-EN 62561-1, which demonstrates its high quality and safety of use. AH Hardt has a management system compliant with ISO 9001:2015 and ISO 14001:2015 standards, which guarantees constant quality control and care for the natural environment.
