hi i've been pondering the idea for a while now but not had the funds to do it. Am thinking of doing a course to get my 17th edition am currently a gas fitter and i know, NO 4 week course can make up for experiance and apprentiship's, i've seen it in my trade! i've dun electrics before house re wires ect altho years ago so have some sort of understanding of the basics an sutch. so my question is if i do my 17th edition can i install electrics or is the 17th just a BS standard to work too and ill need to do a installation and testing course as well as the 17th ?
