As wires for connecting supply voltage segments, use the cable with a cross at least 2mm5^2, three wire (preferably not a wire rope), summarized as relays draw very high current – up to 1A, more diagonal lines will significantly reduce the supply voltage drops on the supply lines.
Kama nyaya kwa kuunganisha makundi voltage ugavi, kutumia cable na msalaba angalau 2mm5 ^ 2, tatu waya (ikiwezekana si kamba ya waya), muhtasari kama relays kuteka juu sana sasa – hadi 1A, zaidi Ulalo mistari kwa kiasi kikubwa kupunguza matone voltage ugavi juu ya mistari ugavi .
