CLASSES OF PLANT AND MACHINERY TO BE ASSUMED TO BE PART OF THE HEREDITAMENT

CLASS 1A

Machinery and plant specified in Table 1A (together with any of the appliances and structures accessory to such machinery or plant and specified in the List of Accessories) which is used or intended to be used mainly or exclusively in connection with the generation, storage, primary transformation or main transmission of power in or on the hereditament.

“Transformer” means any plant which changes the pressure or frequency or form of current of electrical power to another pressure or frequency or form of current, except any such plant which forms an integral part of an item of plant or machinery in or on the hereditament for manufacturing operations or trade processes.

“Primary transformation of power” means any transformation of electrical power by means of a transformer at any point in the main transmission of power.

“Main transmission of power” means all transmission of power from the generating plant or point of supply in or on the hereditament up to and including–

(i) in the case of electrical power, the first transformer in any circuit, or where the first transformer precedes any distribution board or there is no transformer the first distribution board;

(ii) in the case of transmission by shafting or wheels, any shaft or wheel driven directly from the prime mover;

(iii) in the case of hydraulic or pneumatic power, the point where the main supply ceases, excluding any branch service piping connected with such main supply;

(iv) in a case where, without otherwise passing beyond the limits of the main transmission of power, power is transmitted to another hereditament, the point at which the power passes from the hereditament.

(h) Pumping engines for hydraulic power; hydraulic engines; hydraulic intensifiers; hydraulic accumulators. (i) Air compressors; compressed air engines. (j) Windmills. (k) Shafting, couplings, clutches, worm-gear, pulleys and wheels. (l) Steam or other motors which are used or intended to be used mainly or exclusively for driving any of the machinery and plant falling within this Class.

CLASS 1B

Machinery and plant specified in Table 1B (together with the appliances and structures accessory to such machinery or plant and specified in paragraph 2 of the List of Accessories) which is used or intended to be used mainly or exclusively in connection with the heating, cooling, ventilating, lighting, draining or supplying of water to the land or buildings of which the hereditament consists, or the protecting of the hereditament from fire: but in the case of machinery or plant which is in or on the hereditament for the purpose of manufacturing operations or trade processes, the fact that it is used in connection with those operations or processes for the purposes of heating, cooling, ventilating, lighting, draining, supplying water or protecting from fire shall not cause it to be treated as falling within the classes of machinery and plant specified in the Schedule.
