We have an outlet under the kitchen sink that is switched for the disposal but we just bought an Insta Hot and I was wondering if we can make one outlet hot all the time while leaving the other for the disposal, can this be done by just breaking the tab off as you described?


Unfortunately, no. I hate to be the bearer of bad tidings but it is very unlikely that there is a wire in that box that is always hot. It is possible, and you can turn the power off and pull the outlet out of the box to see what is there, but if there are no other wires but those terminated on the outlet you would have to run another wire from the switch to the outlet. Simply breaking the tab off as it is will do nothing but make half the outlet permanently dead, not live.
