Do not apply the rule in Section 430.52(C)(1)(a), which permits the use of the next-size-up protection for branch circuits to motor feeder overcurrent protective devices when the maximum rating does not match a standard size. If the protective devices used for feeder and branch-circuit p...
The graph above illustrates that an inverse-time main ground fault relay may permit a larger size feeder fuse to selectively coordinate with the ground fault relay. In this case the inverse time ground fault relay is set at 1200A, 18 cycle delay. A LPS-RK-200SP amp feeder fuse coordinates...
The easiest way to determine the correct amperage is to select a GFCI with the same amperage as the circuit breaker for that outlet. The other way is to get a wire gauge checker at the hardware store and determine the size of the wires in the circuit. Turn off the power first, of cou...

The Rajasthan and Sirhind feeder canals contribute to the groundwater system, as they are perennial unlined canals. These canals are simulated as a river boundary condition with an appropriate width and depth (Figure ??). Groundwater evaporation was simulated in the model with evapotranspiration (...
