Sounds like a friend of a co-worker last week. They had a new alarm system installed in their 3 year old home in the afternoon. By the evening the house caught fire and was a total loss. Coincidence?
I have actually seen this happen with a friend of mine who owned a hardware store. They just had an alarm system installed where a technician installed a 25 AMP transformer when the specs called for a 5 AMP Transformer.
The technician used smaller wire than what was required with the 25 AMP transformer and the wire heated up and caught on fire.
With all the paint and other items, the store went up pretty quick!
The only way the installer can be held responcible is if it can be proven he drilled through a wire and then tried to cover it up by resetting the breaker as if nothing happened.
If the installer plugged something in and the breaker tripped, then he would not be held responcible.
With that said, im really tired of customers giving blame to the last person who touched a paticular system. For example, I get a customer calling me crying that their system does not work and begs me to come out to do a service call for them. I don't really have time to do the service call because I got better things to do, so I tell them to go call the origional people who installed their system and make it their problem.
Ofcourse the customer can't get ahold of the origional company, so they agree to pay me to come out and fix their system.
I do my Job, get the system up and running and go on my way.
A month later I get a call from the same customer but with now a different problem, and they expect me to come out for FREE since I was the last person who worked on their system.
End result is me going out on one of these service calls and spending twice the amount of time I should have spent out there to fix the system so I don't get any call backs! Its not right!
