should I use on the switch side of a relay? It's for the swith to my electric fan.

Let me first say that im a lightweight drinker and that i've had my first yeager bomb! OMG they are GOOOOD!!

Anyhoo, there are anywhere from 4 to 6 pins on a relay pending the type of relay. What do you mean on the 'switch side?' 85 and 86 energize the coil 30 is the base of the contact and 87 and 87a will show continuity with 30 pending if the coil is energized or not. Most relay's maximum capacity is 30 or 40 amps. If you think you may pull that much choose your wire accordingly. Also be sure to fuse any hot wires going ot the relay. Also placing a one way diode across 85 and 86 will prevent the typical turn off pop that relays can produce from the collapsing magnetic field...

And lest I say WEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE to yet prove my inebreation!!

Switch side small. Power in and out Big

Yeah its that easy

Bumpin' Yota

30, 87, or 87a typically have the larger wires...

Yeah Bumpin' - who would have figured?

Jagermeister = nasty
Red Bull = nasty

Jager+RedBull = good! (expensive in a bar though)

You got a number for small?

4Hummer

this Is what I used for the switch. Its what I had in the garage. I think its like 4 Gauge


Than Amp Wire think it was 4 Gauge, from the battery to the relays and than from the relays to the lights,

I made you a Picture

Two Lights per Relay controlled by one switch.

Michael,

The top wire doesn't look like 4 guage. Looks like 18 or 22 something like that.

4hummer that is 4 guage... this is what i used for my speakers, it works fine until you get to 3000 watts though... once you get to a 3000 w amp you are then going to need a wire called Q gauge.. its about as big as 2quarters together of wire without the red plastic cover... yea its big, but it works, and very expensive.. but i would stick to 4 gauge cause it is easier to work with.. micheal- that is definatly not 4 guage... thats 22 gauge...

Umm Actually it is 100ft of 10 AWG on the roll in the pic. At least that is what it is marked as on the roll in the check of fields (red filled in circles).

Abalagtas- How much current does your relay coil use and how much current can the switch handle? That will be the determining factor for the wire guage to use, but 18/16 AWG should be fine for just switching the coil on and off.

um yeah right...Why do I have a feeling you've told people you blew out your rear window and hit 300+dBs?

there is no such thing as "Q guage." There is 0 gauge 1/0, 2/0, 3/0, and 4/0. After that you get into the MCM field starting with MCM350 and runs through 1200mcm.

the wattage of your amp means nothing, it's the current that it is going to draw vs the lenght of run you have. A 4ga wire over a 20' run doesnt have a snowball's chance in hell at conducting 300amps effectively. (which is what a 3000w rms amp will pull)

If you have more than 800 RMS watts go to 0ga or 1/0, period.

Also the peak power that jensen and now rockford are putting on the amp cases means NOTHING. Look at the rms specs.
