Hello, it all depends on the time of the work, but if the customer bought the materials he would only have to charge the labor and mouths, here the mouths are charged from $ 400 to $ 500, no matter how much it is to place a simple socket. But that is at the discretion and responsibility of each one.
@jilp, I tell you, if it is a big job, those of which you have to change the whole connection, removing the old one and placing the new one. they charge you that and some much more, but if the owner buys the materials, the labor will be cheaper. The materials depends on the quality and the brand. Sintenax cables is the meter about 90mangos the meter, hence the quality of the internal cables depends on everything, such as the sockets, but I reiterate, if the owner buys the materials, the workforce is greatly reduced. I was charged 1200 mangoes for placing an air outlet, I bought the material.
