This Fluke 110V Adaptor Kit features two separate adaptors which have different functions for PAT testing. The first adaptor powers a PAT tester from a 110V supply so that mains-powered testers can be used on construction sites and other areas where a standard 230V supply is unavailable. The second adaptor will permit testing on 110V appliances when used with a Fluke 6500-2 PAT tester.
