Recommended Practice for Hold Down Strap Isolation (R891)
The Recommended Practice for Hold Down Strap Isolation (R891) is based upon its application in cathodic protection systems where the maximum driving potential is 3 volts. In situations where the driving potential exceeds 3 volts, the minimum electrical resistance criteria should be adjusted as determined by the applied potential and current levels.
