DC SPD is cost-effective and provides a solution to improve the system and eliminate any damage caused by surges. It is highly suitable for any facility. It can be used anywhere in the house for protection. These are installed on circuit breakers and automatic transfer switch for portable generator in residential homes and other places […]
MC4 Solar Connector is the name of the connection type on all new solar panels, providing an IP67 waterproof and dust proof safe electrical connection. MC4 Solar Connector will not connect with older MC3 type Connector. The MC4 Solar Connector work best with 4mm and 6mm solar cable. The picture above shows all the parts […]
In an electrical systems, SPDs are usually installed in tap-off configuration (in parallel) between the live conductors and the earth. The operating principle of SPD can be similar to that of a circuit breaker. In normal use (no overvoltage): the SPD is similar to an open circuit breaker. When there is an overvoltage: the SPD […]
A surge protective device (SPD) is designed to protect electrical systems and equipment from surge events by limiting transient voltages and diverting surge currents. Surges can originate externally, most intensely by lightning, or internally by the switching of electrical loads. The sources of these internal surges, which account for 65% of all transients, can include […]
Knowing individual surge components is helpful to understand, but what drives the standards for SPDs are performance aspects or features for each device. After identifying the power distribution system to which the SPD is to be connected, one should compare different available devices by the following: 1. Maximum Continuous Operating Voltage (MCOV). The MCOV is the […]
MC4 connectors are single-contact electrical connectors commonly used for connecting solar panels. MC4s allow strings of panels to be easily constructed by pushing the connectors from adjacent panels together by hand, but require a tool to disconnect them to ensure they do not accidentally disconnect when the cables are pulled. The MC4 and compatible products […]
