Consider an example using the reistance formula:-A copper conductor of length 500 meters is used to supply electrical energy to a lighting load of 1,000W. If the cross sectional area of the conductor is 10mmsq, calculate the resistance of the conductor. ... Therefore resistance of copper conductor = 2.25 x 0.5 =1.125 Ohms Similarly for Aluminium,the meter and the main circuit breaker to the panel boards, where they are split into separate load groups, (i.e., A, B, and C). A fifth wire, the protective earth conductor PE (green) connects the equipment chassis within a load group together and provides a low-impedance, fault-current path back to the sourceThe case has a water resistance of up to 4,000 feet (1,220 metres). The Deepsea version is even protected up to 4,000 metres. Next to its dial inscription and its water resistance, the Sea-Dweller, unlike the Submariner Date, doesn t have a date loupe. Datejust. The Datejust is a classic among the three hand watches.Low Battery Display. ... Mastech MS5209: Analog Earth Resistance Meter. Mastech $ 240.00. View Product. Add to Wishlist. Compare. ...
