Who makes the light hole on the ceiling

Generally speaking, it is opened by an electrician, and the hole is opened according to the size of the downlight purchased when installing the downlight.

Of course, it was the carpenter, the electrician couldn't get it, he was only responsible for wiring and installing the lamps. Of course, if it is due to the electrician not telling the carpenter the size and location in time, and there is no good connection during construction, resulting in the carpenter needing to rework or increase the cost of working hours, then this cost should be counted on the electrician, and he will pay for the carpenter's work.

If the ceiling has been installed, you still have to let the carpenter open the hole, let him open it for you, he does carpentry work, he can do it, electrician does not do carpentry work, if he opens it may damage the ceiling.

Hello! In professional terms, this is a cooperation project, that is to say, to do both in and with these things, or at least the lamps and lanterns are in, the carpenter can understand the installation position, and the opening is because it involves the ceiling structure, and some need to be reinforced, of course, the carpenter needs to be opened, and the level of the carpentry opening is also good. The carpenter said that it would not be opened, because he did not add money or did not say that it was good before, as long as you add some money appropriately, I believe that the carpenter will "open" immediately.
