4 Way Three Phase Distribution Boards – TPN and TP&N

A 4 way three phase distribution board is a popular choice for commercial premises, workshops, retail units and industrial installations requiring multiple outgoing circuits. Also searched for as a 4 way 3 phase DB, 4 way TPN board or 4 way three phase fuse board, these distribution boards are available with main switch incomers, surge protection and alternative enclosure configurations.

What Does 4 Way Mean on a Three Phase Distribution Board?

Unlike a single phase consumer unit, a 4 way three phase distribution board normally provides four outgoing ways across all three phases. This means it can typically accommodate:

  • 4 three pole MCBs, providing four three phase outgoing circuits.
  • 12 single pole MCBs, providing up to twelve single phase outgoing circuits.
  • A suitable combination of single pole and three pole protective devices.

These examples assume standard single-module-width single pole devices. Actual capacity depends on the board manufacturer’s design, device width, phase arrangement and compatibility. Always check the manufacturer’s specifications, particularly when selecting RCBOs or other multi-module protective devices.

Main Switch, SPD and Horizontal 4 Way TPN Boards

Our range includes 4 way main switch TPN distribution boards, selected models with surge protective devices (SPD), and horizontal configurations for installations requiring a different enclosure layout. Check each product for its incoming supply rating, surge protection arrangement and compatible protective devices.

Can a 4 Way Three Phase Board Be Used on a Single Phase Supply?

Selected 4 way TPN distribution boards may be suitable for single phase installations, but only where the manufacturer expressly approves the conversion and provides a compatible single phase conversion kit for that specific board model.

Never mix conversion kits, busbars or protective devices from different manufacturers or incompatible ranges. Follow the manufacturer’s instructions and verify compatibility before installation.

Meter Tails and Cable Entry Glands

If meter tails enter the distribution board, choose an appropriate cable entry gland from our meter tails glands range, including options for single phase and three phase cable arrangements.

We also stock meter tails, including flexible options that can make cable routing and termination easier where space is limited. Always check cable sizing, terminal suitability and installation requirements.
