(*6) - Temperature rise of 125 C (225 F) applies only to impregnatedasbestos insulation if cord is employed within an appliance; cotton

and rayon braids are limited to a. 65 C (117 F) temperature rise.

(*7) - The classes of material used for electrical insulation referred to include materials as follows:

Class A - A Class A insulation system is one which by experience or

accepted test can be shown to have suitable thermal

endurance when oper ating at the limiting Class A temperature specified in the temperature rise standard for the

device under consideration. Typical materials used in

Class A systems include cotton, paper, cellulose acetate

films, enamel-coated wire and similar organic materials

impregnated with sui-table substances.

Class B A Class B insulation system is one which by experience or

accepted test can bE shown to have suitable thermal

endurance when opera.ting at the limiting Class B temperature specified in the t: emperature rise standard for the device under considera tion. Typical materials used in a Class

B system include mica, glass fiber, asbestos and other

materials, not nece ssarily inorganic, with compatible

bonding substances having suitable thermal stability.

Class C - Inorganic materials such as pure mica, quartz, porcelain,

etc.

Class H - A Class H insulation system is one which by experience or

accepted test can be shown to have suitable thermal endurance when operating at the limiting Class H temperature

specified in the temperature rise standard for the device

under consideration. Typical materials used in Class H

systems include mica, glass fiber, asbestos, silicone

elastomer, and other materials, not necessarily inorganic,

with compatible bonding substances, such as silicone

resins, having suitable thermal stability.

(*8) - At a point on the surface of an insulated coil where the temperature

is affected by an external soure e of heat, the temperature rise measured by means of a thermocouple may be 9 F (5 C) (for fractionalhorsepower a-c motors) and 27 F (15 C) (for d· c, Universal, and

integral-horsepower a-c motors) more than the indicated maximum,

provided that the temperature rise of the coil, as measured by the

resistance method, is not more ~han that specified in the table.

(*9) - For a thermocouple-measured temperature on the coil ofa fractionalhorsepower a-c motor (other than a Universal motor) the thermocouple is to be applied to the conducting material, or it is to be separated from that material by not more than the integrally applied insulation of the conductor itself. For a -thermocouple-measured temperature

of a coil of any other motor, the thermocouple is to be mounted as

described above, or it may be separated from the conductor by not

more than the integrally applied insulation of the conductor itself and

the conventional coil wrap normally encountered. Ordinarily, temperatures are to be measured by means of thermocouples, except that

motor-coil temperatures may be determined by the resistance method

if the coil is inaccessible for mounting thermocouples.

(*10) - For an electrolytic capacitor -which is physically integral with or

attached to a motor, the tern perature rise on insulating material

integral with the capacitor enclosure may not be more than 65 C

(117 F).

(*11) - These limitations do not apply to capacitors which are recognized as

being suitable for service at high er temperatures.

and connections during disconnection.

When it is necessary to handle internal wiring

to operate the disconnect, the wiring shall b('

either (1) a type of flexible cord shown in Table V

or (2) conductors suitably jacketed, either individually or as a group, such as with woven fiber

glass. If supplementary jacketing of a group of

conductors is employed, it shall be secured in such

a manner that it will not freely move and expose

the conductors within. The length of the internal

wiring to be handled or exposed shall not be in

excess of 12 inches. For purposes of evaluation of

such a 12-inch section under 1.23.8, it may be

considered as equivalent to one of the types of

flexible cord.
