hello guys i used to be a maintenance electrician for a local council now im fully qualified to city and guilds and have an 18th edition update but i am not a test qualified, but what i want to know is do i have to do a R1 + R2 test and theres a few other tests i was told to do if i change a pendasnt or sw etc if this is true i can understand why so many electricians go out of the trade as its not worth the hastle
