The Megger 1010-851 Test Lead Cable Reel with Earth Spike is designed for use with the DET2/3 Advanced Earth Ground Testers. The cable is wrapped around a reel which features an easy carrying handle for safe transport. Both the smooth unwind and wind action, coupled with the cable's 'feed-through' ability, create a system for easy cable usage during testing. The attachable 10 inch earth spike that is stored on the back of the reel can be hammered into the ground. An unique daisy-chain features aids in creating longer lengths for testing. This cable is colored yellow and measures 100 meters in length.
