I think this CAT-IV rating baloney for outside utility testing is getting a little out of hand, but I guess as long as the employer doesn’t expect you to share some bargain basement harbor freight multimeter with other workers, any decent brand of meter with the required CAT rating should be okay. Just wear your gloves and safety glasses and face shield in case the Chinese made meter innards let go on you at 480V.
Really??
I can't believe I'm reading this from a licenced electrician.
CAT ratings are made for one thing, that being user safety.
The closer you get to the utility system, the larger the magnitude of any surge or fault current is going to be.
I'm not having a go at you, KJay, I'm just sorry you feel this way.
