Abstract:

The present invention provides for a highly reliable circuit, suitable for controlling the delivery of electrical power to a second electrical outlet, based on the power consumption of a first outlet. This circuit has application in home, small workshops and on job-sites where the activation of a power tool, necessitates the activation of a dust collecting device. Because of the compact size, other household applications are also possible. Briefly, a microcontroller monitors the current used by the first outlet. When that current exceeds a first predetermined value, the controller enables the second outlet after a first predetermined period of time. When the current drops below a second predetermined value, the controller disables the outlet after a second predetermined period of time.
