Default Should relays get warm? what causes this?

So i have a 95 ford ranger with a fuel injected 5.0 and 4R70W tranny 203/205 transfer case. My question is that there are three relays under the hood that will get some what hot when the truck is either running or just with the key on and engine off they are the WOT ac cut off relay fuel pump relay and pcm power relay. Is this normal?
Thanks

Of course. If the coil of the relay is energized it's going to get warm.

Correct. A relay is just an electric switch.

So i shouldnt worry that it gets warm then?
I was thinking the same thing but my brother made a big deal of it and i didnt want it to lead to problems down the road (truck burns to ground).

If your using the proper gauge wire,and they have a good ground,dont be afraid of a lil heat,they are "working" they might get hot.
