Dedicated circuit is by no means a requirement, its just an extra step in safety and to protect your tank.
Here is what happens with non-dedicated outlets.
Let's say your tank is running, mid day all lights on, heater kicked in, depending on the tank of course and the equipment this would be different but lets assume you draw 8 amps. Your circuit is limited by both the wiring and matched breaker to 15 amps. Your wife in another room plugs in her iron (to an outlet that's on the same circuit) to get the wrinkles out. Everything on that circuit goes dark (including your whole tank setup). Panic ensues; calls are made to your job, hopefully you are around to answer and walk her through.
Let's get back to apex.
The whole EB8 strip is rated to 15 AMPS, pretty much what a standard household circuit can handle but each individual outlet on that strip is rated up to 5 AMPS except outlets 4 & 8 (10A each). If you group 2 x 300W heaters and plug it into outlet 1, you will melt that outlet and possibly cause fire. Same thing happens if you plug the new 60" LED ATI PowerModule which draws around 980 watts into anything other than outlet 4 & 8 and you will likely have a serious situation on your hands.
Keep in mind that even if the entire strip is rated to 15 Amps, in non-dedicated circuit situation the "capacity" of that circuit goes down with each device plugged into other outlets on that same circuit. Example: there are 4 outlets around the room. 1 provides power to your big screen TV with other equipment (lets assume 3-4 Amps, could be less or far more depending how elaborate your setup is), the 2nd outlet is behind your desk with your desktop computer and dual screen setup (a powerful setup at 3 Amps). That leaves only about 9 AMPs for the outlet behind your aquarium stand and outlet #4 somewhere else in that room. 9AMPS on a larger tank is nothing!
