[QUOTE="water and gas, post: 422536, member: 27931"] So what probe should be touching the boiler L terminal? Are we well checking for polarity here? And do you know how to perform earth impedance on boiler? what is the procedure? As said I am building my gas portfolio through short track course and also new in the trade so even the basic are not there and that's a work in progress, hence why I came over the forum and kindly ask for some clarification. I just need some help and trying to make sense between earth impedence and polarity. Thank you guys [/QUOTE]
