Goods arrived in good shape , inside a carton box each, along with user instructions .. A connection diagram is also printed to the side of the meter. Practically L+N for the voltmeter to work. As for the Ampere- meter the max cable thickness is up to 1 cm , there exists the relevant hole, where the cable leading the power to the "load" has to go through there .. Not tested it yet , have to do some modifications in my panel including a over-under voltage protection , also sold through Banggood

Goods arrived in perfect shape, descent packaging, along with instructions paper in box. There exists a "connection diagram" printed to the side of the item as well. The two screws are for the Voltage meter part, while there exists a hole, 1 cm in diameter, where the cable providing the power to the "Load" goes through it for the Ampere meter part. Nice "large" digits ... Red for the Voltage - Green for the Amperes ... Not installed yet, to test it , as it arrived yesterday .. I plan to pair it with an Over-Under Voltage Protector in my panel ( sold in Banggood as well .. check it out )
