Appliances without any indication asto power consumption

 

Some appliances have no indication as to power consumption; but instead the work load (output) is

*

indicated. In such a case, power

consumption is to beworked out according to thenumerical

formula mentioned below.

Example 1: A 40W fluorescent lampmeansthat its luminous output is 40W. Its efficiency is 0.7 and accordingly, power consumption will be 40 + 0.7=57W. As explained in Item(2), multiply this power consumption value of 57W by 1.2 - 2 and you will get the figure of the necessary capacity of a generator. In other words, a generatorwith a rated output of 1OOOWcapacity can light nine to fourteen 40W fluorescent lamps.

Example 2: Generally speaking, a 400W motor means that its work load is 400W. Efficiency of this motor is 0.7 and power consumption will be 400 + 0.7= 570W. When this motor is used for a motor-driven tool, the capacity of the generator should be multiplied by

1.2to 3 and 570W as explained in the item(3).

NOTES: Wiring between generatorand electrical appliances

1. Allowable current of cable

Use a cable with an allowable current that is larger than the rated input current of the load (electricalappliance). If the input currentis larger thanthe allowable currentof the cable used, the cable will become excessively heated and deteriorate the insulation, possibly burning it out.

Table 7-2shows cablesand their allowable currents for your reference.

2.Cable length

I f along cable is used, a voltage drop occurs due totheincreasedresistanceinthe conductors decreasingthe input voltage to the load(electricalappliance). As a result, the load

can be damaged.w Table 7-2shows voltage drops per100 meters of cable.
