Ensure that the router does not overload the power circuits, wiring, and over-current protection.
To determine the possibility of overloading the supply circuits, add the ampere (amp) ratings of all
devices installed on the same circuit as the router. Compare this total with the rating limit for the
circuit. The maximum ampere ratings are usually printed on the routers near the input power
connectors.
