EEMAC is an association of Canadian electrical and electronic manufacturers formed in 1976 through the merger of the Canadian Electrical Manufacturers Association and the Electronic Industries Association of Canada.
The objectives of EEMAC are;
• To co-ordinate the Association activities in regard to the development
and revision of product standards for the electrical and electronic
industry, with special emphasis on safety, performance and economic
impact;
• To ensure appropriate levels of Government have a good understanding
of the contribution a viable electrical and electronic manufacturing base
can
make to Canada’s industrial and social development;
• To provide its members with ongoing programs directed at developing
greater understanding on the part of the public, customers and governments of the contributions, concerns and problems of the Canadian
electrical and electronic manufacturing industry;
• To develop and disseminate information about the industry and its
markets to members, government officials and the public;
• To develop a working relationship with other trade associations to
ensure optimum support and co-operation when required.
EEMAC Standards are developed in co-operation with various segments
of the electrical industry, such as inspection authorities, utilities, user
groups, consultants, CSA and with other interested parties including government agencies.
The main objectives of the Standards are:
• To encourage uniformity in equipment nomenclature, performance,
rating, dimensions, and test methods.
• To assure users that the equipment complies with established performance, safety, rating, and capacity criteria.
• To ensure economies to users through the interchangeability of equipment and the reduction of inventories.
• To provide users with the benefits of low-cost, high-volume production techniques inherent in product standardization.
EEMAC Standards represent a consensus of all interests and are widely
used throughout the industry on a voluntary basis.
EEMAC Standards are subject to periodic review to ensure consideration of the latest technological advances. Suggestions for improvement are
invited and should be forwarded to the EEMAC office.

PREFACE
This new edition of Standard E14 supercedes the previous edition
published as CEMA Standard E14—1, 1972.
This Standard adopts a n~n~berof NEMA Standards*, by reference,
with exceptions. The exceptions are included in Clause 1, General
and on individual exception sheets.
The latter are punched so as
to permit insertion in the NEMA Standard facing the page to which
they apply.

TEMPERATURE RISE OF CONTACTS
The temperature rise of contacts above the ambient temperature,
when the contacts are tested in accordance with their ratings, shall
not exceed the limits such as are established by the CSA Standard
C22.2 No. 14. The temperature rise shall be determined by the thermometer or thermocouple method (see ICS 1—109.10.03). This Standard
does not apply to contacts which are mounted directly on resistor
elements.
ICS 1—109.14
TEMPERATURE RISE OF BUSES AND CONNECTING STRAPS
The temperataure rise of buses and connecting straps, above the
ambient temperature, when this equipment is tested in accordance
with its rating, shall not exceed limits such as are established
by the CSA Standard C22.2 No. 14. The temperature rise shall be
determined by the thermometer or thermocouple method (see ICS

RATING, PERFORMANCE, MANUFACTURING

VOLTAGE RATINGS
Voltage ratings for industrial control apparatus are based on utilization voltage and shall be as follows:
(a)
Alternating Current, 60 Hertz, Multiphase
115, 200,
230, 400, 460, 575, 796, 920, 2300, 3300, 4000, 4600 and
6600 volts.
(b)

(c)
Alternating Current, 60 Hertz, Single Phase
230 volts.
(d)

(e)
Direct Current
—

—
380 volts.
—

—
220 volts.
115, 230 and 550 volts.
Voltages for resistance welding control higher than 230 volts shall
be 460 and 575 volts.
Alternating—current voltages are based on CSA Standard No. C235—1969,
and reflect the fact that industrial control is normally applied
at the point of power utilization. Individual manufacturers may
choose to mark coils or control—circuit transformers at the utilization voltage (listed above) or at the corresponding nominal system
voltage (120, 208, 240, 416, 480 or 600 volts, 60 hertz).
Coils
marked with voltage ratings in multiples of 115 volts are considered
adequate for use on nominal system voltage ratings in multiples
of 120 volts.

Overcurrent Protection and Disconnecting Means.
6.8.1 A fused main switch or circuit breaker capable of being
locked in the open position shall be connected in the supply circuits
on the crane immediately ahead of all control equipment.
This device
shall simultaneously interrupt all supply conductors and shall be
located conveniently for the operator and maintenance personnel
on cab controlled cranes.
Conductors between this device and the
main collectors shall be enclosed in a conduit or raceway separate
from all other circuits.
6.8.2 The horsepower rating of the main switch, or circuit
breaker shall be at least equal to the horsepower of the largest
motor (or largest combination of motors which mustoperate together)
plus 1/6 of the sum of the horsepower ratings of the other motors
if ac, or plus 1/4 of the sum of the horsepower ratings ‘of the other
motors if dc, and shall in no case be less than 50 per cent of the
sum of the horsepower ratings of all the motors.
Note:
In applying switches under Clause 6.8 the conditional
horsepower ratings of switches having such ratings based
on the use of time—delay fuses may be used.
6.8.3 Where the requirement of the switch as determined from
Clause 6.8.2 exceeds 50 horsepower (100 hp in the case of a three—
phase ac supply) the ampere rating shall be as follows, except that
it shall be not less than the minimum ampere rating permitted *for
a 50 horsepower (100 hp in the case of a three—phase ac supply)
