David Etukudo Corner Grounded Delta
A corner grounded delta system is a three-phase delta service with one phase having the ground connection. This configuration goes by several names including grounded leg/phase service, end-grounded delta system,…
Aluminum vs Copper Wiring
The comparison between aluminum vs copper wiring is always on the front burner when it comes to electrical design. Although they are both good conductors, copper usually has the upper…
How to Size a Wire for 600 Amp Service
Selecting the appropriate wire size is critical for the safety and efficiency of any electrical system. For a 600-amp service, the appropriate wire size would be 1,500 kcmil-gauge. However, there…
120V vs 220V
120V and 220V are both standard power supply voltages. Supply from any of these systems has unique features that make one suitable for an application over the other. Although the…
50Hz vs 60Hz
Power supply standards vary with countries/regions, especially when it comes to voltage and frequency. In the case of frequency, the 50Hz vs 60Hz are both valid supply standards. In this…
Shunt Trip Breaker Wiring
Proper wiring of a shunt trip breaker is necessary for it to perform its role of protecting all downstream devices in its circuit. Although it performs the same function as…
Single-phase vs Three-phase
Single-phase and three-phase configurations are currently the most common AC power supply systems in use. Because each system has advantages over the other in certain applications, it is necessary to…
Service Factor – Application, vs. Power Factor
There is a lot of misunderstanding about the service factor concept in the industry. Some take it to be solely a periodical excursion into overload conditions, while others consider it…
2-Phase vs 3-Phase
2-phase and 3-phase electricity are common configurations of transmitting power from one location to another. Although they are both alternating current systems, each of them have features that are suitable…
