Pvc Gland Size Chart Design Talk 1 hp = 746 watt. 746 (220 x 0.95) = 3.56. so it's will take is starting time double current 3.56 x 2 = 7.12. so the suitable size of electric cable is 2.5 mm according table 1. so our total load is 52 amps, so the suitable size of rcd circuit breaker is 63 amps and double pole main circuit breaker is also 63 amps. We have to account for the 80% breaker rule. this means that these 12.5 amps should represent 80% of the breaker amps. to calculate the size of the circuit breaker needed, we have to multiply the amp draw by 1.25 factor like this: minimum circuit breaker size = 12.5a × 1.25 = 15.63 amps.
Wire Size For 20 Amp Circuit Breaker In this video we will tell you about the size of the load size and breaker size and the size of the glass by the cable size.are you confused about wire size. Select a breaker with a current rating greater than or equal to the load current to determine the appropriate circuit breaker size. for a load current of 8.33 amps, a 10 amp circuit breaker would be appropriate. however, if there are no 10 amp breakers available, the next size up (i.e., 15 amps) can be used. 3. An exact 100% rated for 30a circuit breaker can be used for 30a non continuous load. example 2: cb size for 28a contentious load. in case of continuous load, rate of %125 is applicable. 1.25 x 28 a = 35a. example 3: cb size for 30a non contentious load & 28a contentious load. = 125% continuous load 100% non continuous load. Start by locating the size of your cable in the rows. once you’ve identified your cable size, cross reference it with the number of cores in the cable. the intersection of these values on the chart will indicate the required size of your cable glands. it is important to note that cables can range between 1.5 mm 2 and 1000 mm 2, and the number.
