Hello,
In the US there is a certification program "NICET" to certify technicians & designers for codes & standards knowledge.
It is sometimes called out in a specification that the design and installation shall be done by a certified technician.
Is there a program set up in Europe?
I am interested in installation practice differences in other areas of the world, different products that are available and technologies that are used. Always keeping options open for new horizons.
