Grounding and Jumper Cable

Protective grounding devices might look indestructible, but they aren't. Like many live line tools, grounding equipment can become compromised through regular use, age, exposure to sharp objects, dirt, oils, petroleum-based products, environmental fluctuations, improper storage, abuse, and electrical arcing to name a few.

For these reasons, daily visual inspections are required before every use to keep users safe and to check if damage is suspected. To keep existing ground sets performing safely, annual testing is highly recommended. Testing is required if damage is suspected.
