i have an electrical outlet that has a 5 plug adaptor plugged into it. The adaptor has two lights, one which says protected and the other says grounded. everything will be fine for a while and then all power to the unit will disapear and the lights on the adaptor go off. Last time this happened i replaced the outlet and everything was peachy keen until it recently failed again. The outlet still seems to work if the adaptor is pushed hard against it, but not to work regularly. I was wondering if i could replace the outlet with one rated for a higher amperage or even a gfci outlet and would this help the problem. the outlet has a phone, answering machine, toaster oven and coffeemaker running on it, and we try to not run the toaster oven and the coffemaker at the same time. What would cause the outlet to repeatedly fail and how can i fix the problem? thanks.
