Twinflex / Ripcord

0.5mm wire (sold per meter)

To reduce DIY costs and power connection points, use 30A connector strips to join 2x lighting chains.

The 30A connectors are big enough for the 2-pin plug to fit into the connector tightly (no need to cut and strip lighting chain wires).

You can then take power from one connection set, and to other multiple connections sets (using twinflex wire).
