UPS Proven Useful I gave a score card which showed that the UPS was a good thing. The situation now is:
Circuit Breaker: 2
UPS: 3
Sparky: infinity
A sparky mate came round this morning and installed an additional two circuit breakers.
It turns out there are actually 5 different circuits in the house, but they are shared over 2 circuit breakers. And one circuit breaker has all the power outlets we put high loads onto (heaters, dryer, computers, microwave, A/V gear). One of those circuits is only an external RCD protected power socket.
Now we have 5 circuits on 4 breakers (the outside power socket shares a breaker with an internal, low use, circuit).
Hopefully we won't have any further issues with breakers blowing!
