As the title suggests, my power is incredibly dim, and even flickers off when i power on an appliance. There wasn't a problem until the purchase and use of a portable radiator heater. After using it for an hour, the power dimmed, and unplugging the device hasn't helped. The power company checked everything on their end, and everything is in order. This is an older home, with a fuse box that uses four 25 amp fuses. Changing these fuses hasn't helped. The electric stove won't even come on anymore. Any help or suggestions would be much appreciated.
