Choosing the right distribution board for a three-phase EV charger might not be glamorous, but it’s absolutely critical. A well-chosen board keeps the installation safe, compliant, and reliable.
First off, you need to consider the current rating — make sure the board can safely handle the total load from the charger and any other circuits. Overloading a board is a big no-no and can cause serious issues down the line.
You also want to make sure there’s enough room inside for protective devices like PME monitors, RCBOs, and surge protection devices (SPDs). Some boards even come with PME monitoring built-in, which is a neat way to save on extra devices and wiring.
Don’t forget price — there’s a balance between cost and quality. Eco Harmony’s range offers durable boards that tick all the boxes without breaking the bank.
