GSM Outdoors 400A 12V Power Distribution Block 2 in 1 Accessory

SKU CH-YDST-H0EEY

A 400A power distribution block with tinned copper bus bars, protective covers and multi-angle mounting for 12V DC systems up to 48V or 300V AC

  • Handles 400 A continuous current for demanding 12 V systems
  • Tinned 8 mm copper plate delivers high conductivity and corrosion resistance
  • Torque-resistant mounting keeps copper bar firmly bonded to base
  • Protective cover shields live terminals while allowing multi-angle wiring
  • Colour-coded red and black bars simplify circuit organisation and reduce short-circuit risk

400A 12V power distribution block

This 400A power distribution block provides heavy-duty positive and negative busbars for 12V DC systems rated up to 48V DC or 300V AC. It is built for automotive, marine and RV electrical installations that need a single, compact point to consolidate multiple high-current feeds.

Four M8 studs and six #8 screws

The block uses an 8mm thickened tinned copper plate for high conductivity and corrosion resistance. Four 5/16 inch (M8) terminal studs handle main power cables, while six #8 terminal screws accept smaller branch circuits. The design withstands high tightening torque without separating the copper bar from its base.

Red and black covers with side access

A pair of colour-coded protective covers shields exposed terminals to reduce accidental contact and short-circuit risk. Openings on both sides allow cables to enter from multiple angles, keeping wiring neat and adaptable to tight compartments.

Questions about this item

Will the 400A rating handle the load from my existing 12V battery bank?

The block is rated for 400A and supports up to 48V DC, so it matches a typical 12V bank as long as your total draw stays within 400A.

How can I verify the bus bars are conducting properly after installation?

With power off, check that all four 5/16" studs and six #8 screws are tight, then measure voltage drop across each bar under load; a negligible drop confirms good contact.

Does the package include both the red and black bus bars and the protective covers?

Yes, the set supplies a pair of bus bars (positive and negative) with their protective covers; you only need to provide your own ring terminals and cables.
