full loadn.adj.

Brit.

/fʊl ˈləʊd/, U.S.

/ˌfʊl ˈloʊd/

Origin: Formed within English, by compounding. Etymons: full adj., load n.

Etymology: < full adj. + load n.

A. n.

With reference to an electrical device: the state or condition of operating at the maximum output the device is designed to be capable of; the state or condition of drawing or supplying the largest possible current that can be sustained safely. Cf. overload n. 3.

1888 Abstr. Proc. Soc. Arts 1887–8 (Mass. Inst. Technol.) 46 Comparing the maximum loss in this auto-converter with that in the standard induction coil under full load..we have, for standard coil, a waste of energy as follows [etc.].

1891 Electr. Engineer 7 Jan. 7/2 The automatic motors are plain shunt wound and there is but a slight variation in speed between full load and no load.

1944 Jrnl. Inst. Power Engin. 91 145/2 On the input side there is a split-phase arrangement which on full load converts from single-phase to two-phase.

1987 E. H. J. Pallett Aircraft Electr. Syst. (ed. 3) iii. 62/2 The difference between the output terminal voltages at full-load and no-load, with a constant input voltage, is called the regulation of the transformer.

2015 A. Waygood Electr. Sci. for Technicians xii. 288 For generators designed to operate at, or near, full load, manufacturers design their machines so that maximum efficiency occurs at full load.

B. adj.

Corresponding to or involving the operation of an electrical device at the maximum output it is designed to be capable of; designating the largest possible current that can be drawn and sustained safely; (also) corresponding to or involving such a current.

1892 Electr. Engineer 23 Mar. 308/2 The total loss need not exceed 25 per cent. under full load condition.

1922 Jrnl. Amer. Inst. Electr. Engineers 41 321/1 Few brakes in service could be depended upon to release at less than 75 per cent of full-load current.

1953 Pop. Sci. Oct. 195/1 The drill has a geared chuck and a two amp. universal motor. Its no-load speed is 2,100 r.p.m., and its full-load speed is 1,000 r.p.m.

1968 IEEE Trans. Power Apparatus & Syst. 87 1456/1 The voltage rating of 14.4 kV (with a calculated full-load voltage of 15 kV) was selected to take full advantage of the 15-kV insulation class.

1993 J. H. Matthews Introd. Design & Anal. Building Electr. Syst. iii. 135 The starting torque for 1800 RPM motors ranges from 80 to 275% of the motor's full load torque rating.

2015 G. Nicholl & M. J. Boss Electr. Safety iii. 30 The full load current can be calculated by dividing the capacity of the transformer by the rated voltage of the second winding.
