An electrical outlet for supplying electrical power to one or more loads is provided with a reed relay, an alarm indicator, one or more receptacles, and a pair of input terminals connected to power source to provide power to the one or more receptacles. The reed relay comprises a reed switch and a coil around the reed switch. The coil is coupled between one of the two input terminals and the one or more receptacles and configured so that the coil can generate a sufficient magnetic field to drive the reed switch to actuate the alarm indicator to give an over-current warning to a user of the electrical outlet when total amount of current flowing through the coil and consumed by the one or more loads connected to the one or more receptacles exceeds a predetermined level of current.
