electrical help: garden lights blowing circuit

silvercar

Discovered that one of the circuits keeps tripping. Turns out that its the switch that operates the outside lights and the summer house at the bottom of the garden. I've switched that off (isolator inside the house) and the electrics turn back on so I've identified the problem. Can someone confirm that its safe to turn the electrics back on with that switch off? I hope so because the boiler is on that circuit!

What next? Absolutely pouring with rain at the moment, as well as dark. The isolator switch takes the electrics from the house down to the bottom of the garden where it then provides electric for the summer house, shed and security lights. Only thing that would be switched on at the moment is the security lights on the outside of the summer house, operated from inside the summer house. I'm guessing water has got in to a cable somewhere? Any ideas where I would start looking? There is 200 foot of cable underground!

Sounds ok. The switch itself is the isolator. Then it's not the 200' cable run but something else or water in something or a mouse eat the cables?

Just had a thought, it could be as simple as a security light bulb blowing and flipping the circuit switch inside the summer house RCB which in turn would flip (maybe) the switch in the main RCB.

I'll investigate in the morning.

Inspection led to nothing.

Turned the isolating switch back on and everything works, even the PIR light.

All the flippy switches in the consumer unit in the summer house were set corectly, nothing had flipped.



To explain the layout.

The main consumer unit in the house had a flipped switch. Near the main house back door is the isolator switch to turn off the electrics to the summer house. Turning this off allowed me to reset the main consumer unit. 200 feet away is the summer house with its own consumer unit, all the switches were set correctly in this, which led me to believe that the problem must be sumewhere between the summerhouse and the main house.

Electrics on this part of the house are recent; 2006 for the main consumer unit and 2004 for the in house electrics and summer house.

No news is good news.
