Application
This product supports metering of various meter-position, after mounting, it not only avoids the problem of weak current, unsafe, inconvenience or other potential accidents caused by service-entrance wire entering into bare copper bar directly, but also cuts down the cost of metering box. It can be divided into single-pole (1P), single-phase (2P), three-phase three-wire (3P), three-phase four-wire (4P) according to the pole number; it can be divided into one-outlet, two-outlet, three-outlet, four-outlet … twenty-four-outlet and so on according to the outlet wire condition.
