Questions

How do I choose the current rating (amps)?

Add up the power of everything you will plug in, divide by the voltage, and pick a rating above that. Heaters and other heavy loads usually belong in a wall socket, not on a board.

What does conductor thickness (mm²) change?

Thicker conductors carry more current with less heating. Our configurator blocks any combination where the wire is too thin for the chosen amps, using a conservative table.

Does cable length matter?

Yes. Long runs lose voltage, especially at high current. The configurator warns above 10 m at 16 A or more, so talk to an electrician about thicker wire.

Single phase or three phase?

Most homes and offices use 230 V single phase. Workshops with three phase machines may need 415 V. kW capacity is calculated differently for each, assuming a power factor of 0.9.

What does made to order mean?

Custom boards are assembled after you request them, so we confirm the spec, price and timing with you before anything is built. No payment is taken on this site.

Are the values on this site final?

No. Specs, prices and ampacity values are placeholders and must be confirmed by a qualified electrician before you rely on them.
