Quick Electrical: Fans & Amps

I just want to be sure this is right:

All the fans Im concerned with are 12v (dc) and require 0.15 amps (besides one that needs 0.6)

I just want to be sure Im covered with one 12v (dc) 1.5 amp adapter

(0.15x6)
.9
.9 +.6
=1.5 amps

So I can splice the adapter cord several times to get all of the above going off one outlet/adapter?

Thats how electricity works, right? :)

Thanks

edit: 80% rule - thats for circuits and actual wiring, not for appliance use; 1.5A means it handles 1.5 safely, verdad?

But im not sure what fans you are using, plus it always good to give some cushion, if you need 1.5 amp you should have a 2 amp just in case. im a auto tech , so most fan motors i work on in the 12v range are rated at 15 amps each. you using computer fans?

Yeah, (computer) case fans, maybe 4 inch length and width.

So when you wire fan motors do you attach more than one to a given power supply?

eg. 2x 15a fans to a 40a supply?

You jus strip a portion, tie em together an tape? In a business atmosphere you probably use connectors and pieces that assure your liability but I mean.. in this sense, would cuttin them in work aright?

Just make sure you hook everything up in parallel configuration and not series. I have drawn a diagram for you just in case it was confusing.
