Test Power Cable for EG4xxx (Core/Pro) Meters (with international adatpers).
This cable may be used to power the eGauge for pre-install configurations, to obtain data from an eGauge after being removed from an installation, or can be used to power the eGauge if AC power or voltage measurements are not needed.

When measuring AC power, the AC voltage inputs must be utilized, power cannot be calculated otherwise. The Test Power Cable may be used to power an eGauge while it is measuring high voltage, but the AC inputs (L1/L2/L3/N) must be connected to the system being monitored.
