# Slow-Start Power Socket
|
|
|
|
If connecting all your devices at the same time is tripping a circuit breaker, you need a *slow-start power socket*.
|
|
|
|
This device controls a strip of power sockets, enabling them individually one by one with a delay. This way there is a much smaller spike in electricity usage, which helps to avoid tripping the circuit breaker.

## Overview
|
|
|
|
A microcontroller is powered from a 5V brick (always connected). It controls a set of relays, which in turn enable power to individual power sockets. Upon boot the microcontroller waits a few seconds before enabling each of the power sockets. Then it sits idly by until the next power outage. All of this is enclosed in an electrical distribution box.
|
|
|
|
Optionally a speaker is used to indicate the state of the power socket "boot" process. A circuit breaker may be added to guard the whole device from tripping the main circuit breaker in the building.
