Joint Guard* Protection system
ABB/GE’s Joint Guard protection system shows you, with color, whether a busway joint is loose or tight. The center spot is bright red when a joint is loose and turns black when proper torque is applied.
It does this not just once — as with double- headed break-off bolts — but even after the repeated tightening and loosening so often required during installation. Even without a torque wrench, you’ll know when it’s tight and when it’s right. And it will keep on working that way for 30 years.
