3 selection instructions

According to a current and bus cross-section and other parameters to select the corresponding specifications products. One wire crosses the transformer window. Remove the top of the transformer wiring cover, remove the lead gasket, the second lead after the shell reset. Metering energy can be used with fixed bolts and hood on the hole sealed seal to prevent theft.
