4.6 Electrical data
4.6.1 Electrical data: single-phase pumps
When you start a cold pump, the motor will draw the start-up current shown in Table 5 for several seconds. A slow-
blow fuse is required to prevent fuse failure during pump start-up. Within five minutes, as the oil and pump warms
up, the current drawn will slowly reduce to the full load current specified in Table 5.
