Simple circuit wiring, proper method?

[xboxhaxorz]

So i have a 220v power supply that is powering several devices

From the 12v + line i have a wire going to a spade connector, out of that butt connector is another wire that goes to an led that draws .9 amp

The female spade connector is connected to the fan which has a male spade connector that draws .6 amps

Is that safe, or will the led pull .9 amps. through the wire which will go to the .6 amp fan and overload it?

The amperages are used for informational purposes and not the exact amperages FYI

I also have a 12v switch, which is controlling 2 fans at .3 amps and .8 amps, from the switch output should i have 2 different wires going to each fan or should i just use a single wire which goes to the closest fan and have the other fan connect to the pos and neg points on that fan

I am trying to get a drawing, but my skills lack in that area and its not coming out the way i want it too

Re: Simple circuit wiring, proper method?

spade connectors are rated at many amps - usually 10 or more.
the weak point is more likely to be your switch

Re: Simple circuit wiring, proper method?

Both are rated high enough, im just wondering if the wiring should be done differently

Now that i look it over again i realize devices will only pull the amperage they need, i just need to figure out why a fan blew

Current, or amperage, should be the same in the circuit all over, except for parallel circuits. For the parallel circuits, the sum of the branches in the parallel circuit should equal the total current for the circuit.

Here's a site that I used when I was learning about it. It's fairly good:

That's just for the parallel circuit. For the serial circuits, http://www.physicsclassroom.com/clas...eries-Circuits

If you could draw a schematic, it would be a lot more helpful. There are programs that can help with this if you don't want to physically draw it by hand with a pen or pencil. Eagle is one such program.

You are correct with your statement that it is in the components that determine the amount of current that is needed to drive the circuit. If your circuit requires 200mA of current, you can safely go over that and use 800 Amps if you wanted, it would only use 200mA. The 800 Amp would be over kill though, but it wouldn't hurt the circuit at all.

Re: Simple circuit wiring, proper method?

Do you have 12VDC going directly to the LED? Or do you have a resistor in there somewhere? 12VDC seems real high for an LED. Can you share a datasheet for the LED and the fans?

And when you say spade connectors, are you talking about something like this?

If you can't do the schematic, maybe you can share a picture of the actual circuit.

Thanks!
