Gate motor circuit

[Derlyn]

I have a situation where the buyer of a house for which I produced the COC, insists that the gate motor must be on it's own seperate circuit.

It is presently wired to a plug circuit and has an isolator next to it.

How do I prove to him that how it is presently wired is acceptable, or am I missing something ?

Request him to show you were in the regulations it states that it must be on it's own circuit or how he got to make that statement
There is no where

Gate motor falls under fixed appliances and there are specific fixed appliance's that state that it must be on its own dedicated circuit , like Aircons over 16 Amp , Cooking appliances over 16 Amp etc
It is actually stated at the beginning of the specific section

6.16.3.2.1 A dedicated circuit(s) shall be provided for cooking appliance(s)
that are rated at more than 16 A


On motors the regulations are quite on dedicated circuits which implies there is no such restriction - Logically if a circuit to an aircon or stove under 16Amp does not have to be separate then a clock motor, gate , garage door motor would not have that requirement
A gate motor has built in protection and would not require the circuit protection to be sized accordingly as per 6.16.5.1.1




6.16 Fixed appliances
6.16.1 General
NOTE The general requirements in 6.16.1.1 to 6.16.1.12 (inclusive) apply, except
where otherwise required for specific cases.

6.16.5 Motors
NOTE Motors include the motors in automatic doors and gates, garbage disposal
units, pumps (pool, fountain, spa, etc.), and the like (see also 6.16.1).

6.16.5.1 Motor protection and control
6.16.5.1.1 In addition to the requirements of 6.7, the circuit that supplies a
motor shall have overcurrent protection unless the motor
a) forms part of equipment that has built-in overcurrent protection,
b) has an integral thermal protector with an accessible reset button,
c) has an automatic resetting thermal protector and there is no likelihood of
mechanical damage or of injury to persons when the motor restarts, or
d) is of a high impedance type that can stall without overheating (such as the
motor of an electric clock).


6.16.5.1.4 Each motor shall be supplied by a manually operated disconnector
or any other manually operated disconnecting arrangement such as a
withdrawable circuit-breaker, a removable link, a fuse or by the removal of a
plug from a socket-outlet, which provides at least the same isolating distance,
for the sake of safety, as a disconnector that is
a) readily accessible and mounted on or next to the motor, or
b) visible from the motor, or
c) lockable in the open position, or
d) housed in a lockable enclosure other than a distribution board.

Thanks GCE.

I couldn't see myself being wrong on this one, but you know how your mind plays games when you are confronted.

The buyer works at Daimler Chrysler and one of those who thinks he knows everything.
