what size relay?

Post by **Alex** » Thu Jul 03, 2008 2:51 pm

yo my home-boys,

just a question about relays, what amperage would be suitable to run 3x spotties (a big lightforce and 2xcibies with 130w globes) or should i be running two seperate relays?

Not sure what size ive got now, but it seems to be coping alright. I just dont wanna melt anything haha.

thanks.

add up all watts you want to run then divide by 12 (volts ) = minimum amperage relay to use

ie 130 x 3 = 390
divided by 12 = 32.5 minimum
hope that helps/makes sense

Stardard relays are usually about 30 amp. One relay per pair is usually pretty standard... i have never seen a system with one relay per spot light. Go one for your big daddy and one for the pair of cibbies. These relays are found at any car shop or Dicks smiths.
