The people doing our gardens where my holiday house is, requires an external 220V outlet with at least a 15Amp circuit breaker. The problem is that they trip this breaker every time they use it. To make matters worse the whole lot trips. This is what I have currently in place. I whole row of breakers from small to large to try and protect my mains. This is not working when there is a dead short.
Lawnmower -> 15Amp (outside breaker in IP55 enclosure) -> 20Amp breaker (DB board) -> 30Amp(Db breaker) -> mains breaker.
I tested it again this weekend with a dead short. 1 out of 3 times the 15Amp breaker will trip on its own. During the other times, all the breakers trip all the way from the mainboard down to the smallest one. I do not understand why but accept this is the scenario with a dead short. I presume with power overload the smallest will trip first. I did not test this.
I know it should be easy to say tell the people to check their leads. We all have done this many times trying all sorts of emotions etc. without any success. We cannot change to someone else as no-one else is prepared to drive the distance. We are 30km gravel road to the nearest town.
Every time this happens it is a 500km round trip to sort out the electricity. Without electricity our pumps stop working and everything dyes within two weeks. It is 40+ degrees in summer. No one is prepared to leave keys so that circuit breakers can be reset by 3rd parties as we have had problems in the past doing this.
My question is this: How can we protect the mains from a dead short and provide the garden people the facility to reset a breaker that has tripped.
Hopefully there is someone here with enough electrical experience to help.
