@RSJB18 posted:Here are the covers. They are available in various colors and lengths. They help to protect the cord from physical damage too.
If the circuit you are plugged into is fed by a 15 amp breaker, then the cords and power strips would be fine at the same rating. Typically a good extension cord or power strip with 14/3 SJOW cable is fine. Flexible cords cannot be run concealed in ceilings/ walls by code. Stringing it along the ceiling is acceptable as long as its visible.
Splitting the load on two different receptacles and cords is not a bad idea either.
You also cannot plug one power strip into another to daisy chain them.
