Subject: Circuit breaker down
====== Circuit breaker down ======

The second circuit breaker was down due to the current limit: 15 A

The reason was that all of oscilloscopes are connected in one power tap (maximum 15 A current with 100V = 1500W).

Estimated power consumption from 6 oscciloscopes is around 3kW.

The power tap was down after the scope is about to boot (windows -> scope software), so I expect the power consumption became a peak at that time.

As a result, the fuse in the power tap was burned.

We called PF-AR organizer (Ext. 2493) and took the photo -> we should calculate the total power consumption well and distribute considering the current limit.
