An ETPN DB (Earth Terminal Pole Neutral Distribution Board) is a type of
distribution board commonly used in electrical installations for managing the
distribution of electrical power within a building. It typically includes the
following features:
1. Number of Ways and Modules: ETPN DBs come in
various configurations, such as 4-way, 6-way, 8-way, and more, each supporting
different numbers of modules. For example, an 8-way ETPN DB might support 8+24
modules (Power Factor Shop) (Power Link).
2. Mounting Options: These boards are suitable for
both flush mounting and surface mounting, making them versatile for different
installation environments (Legrand) (Power Link).
3. Components and Accessories: They are equipped
with components like a 100A copper busbar for each phase, neutral bars, earth
bars, cable ties for cable management, and fully insulated busbars and shrouded
neutral bars. Some models come with reversible doors for added flexibility in
installation (Legrand) (Power Link).
4. Compliance and Ratings: ETPN DBs typically
comply with standards like IEC 61439-3 and are rated for IP43 protection,
indicating good protection against dust and water ingress (Legrand) (Power Factor Shop).
These distribution boards are essential in ensuring safe and efficient power
distribution in residential, commercial, and industrial settings.
