Tecnoseal PMSEAGROUND4 Marine Grounding Plate – Porous Bronze 455x150 mm

Tecnoseal PMSEAGROUND4 Marine Grounding Plate – Porous Bronze 455x150 mm

The Tecnoseal PMSEAGROUND4 is a rectangular marine grounding plate manufactured from porous bronze alloy. It is designed for onboard electrical grounding applications and provides a conductive grounding surface for compatible vessel electrical installations.

The plate measures 455 mm (17.91 in) in length, 150 mm (5.91 in) in width and 13 mm (0.51 in) in height. Its rectangular body incorporates four mounting holes arranged in two pairs, with longitudinal and transverse centre-to-centre distances of 255 mm and 75 mm respectively.

The manufacturer specifies a grounding surface rating of 8.00 m². The PMSEAGROUND4 weighs 4.60 kg (10.14 lbs) and is intended for installations requiring a larger grounding plate with a four-hole mounting arrangement.

Technical Specifications

Porous Bronze Construction

The Tecnoseal PMSEAGROUND4 is made from porous bronze alloy, as specified in the manufacturer catalogue. This material forms the conductive structure of the grounding plate for its intended marine application.

The manufacturer-listed surface rating of 8.00 m² is a grounding surface specification and should not be confused with the geometric area calculated from the plate's external dimensions.

Marine Electrical Grounding Applications

The PMSEAGROUND4 is intended for grounding onboard electrical devices as part of a suitable marine electrical system.

Its larger dimensions and manufacturer-listed grounding surface rating distinguish it from smaller PMSEAGROUND models. Selection should be based on the vessel's grounding system requirements and the equipment manufacturer's specifications.

Four-Hole Mounting Configuration

The plate features four mounting holes arranged in a rectangular pattern. The manufacturer specifies a longitudinal centre-to-centre distance of 255 mm and a transverse centre-to-centre distance of 75 mm.

The mounting hole diameters are not provided in the available catalogue data. Before installation, confirm the required fasteners, mounting surface and grounding connections.

Installation and Maintenance

Installation should follow the vessel electrical system design, equipment manufacturer's instructions and applicable marine electrical standards.

The grounding plate and its electrical connections should be inspected periodically to verify their condition and ensure that the installation remains suitable for its intended purpose.
