AS/NZS 61439 Compliance

NHP MOD6+ panelboards are designed and verified to meet AS/NZS 61439

Important Notice: If a user modifies the panelboard outside the scope of the NHP design then they are deemed to be the assembly manufacturer and are responsible for compliance with AS/NZS 61439. The installer needs to pay close attention to the AS/NZS 61439 standard that the panelboard complies with. Specifically, AS/NZS 61439.2 and AS/NZS 61439.3. The main differences are stated below:

AS/NZS 61439.2 Requirements	AS/NZS 61439.3 Requirements
Any current rating (1)	Current rating not exceeding 250A (InA 250A)
No current limit on outgoing circuits	An outgoing circuit not exceeding 125A

(Inc 125A)
Specified to have a form of separation| No form of separation (2)
| Intended to be operated by ordinary persons
Outgoing protective circuits must be suitable to be operated by ordinary persons (example: MCBs to AS/NZS 60898)

NHP’s MOD6+ Range is available in 160A, 200 and 250A
If required, the panelboard must conform to AS/NZS 61439.2

Environmental Requirements

MOD6+ panelboard should be installed in a suitable ventilated environment. Each panelboard range has a particular ingress protection rating which should be considered when selecting the mounting location along with the local environmental conditions. The installer should be guided to assess that the product they are installing suits the environment is installed.

Important Notice: Do not install the panelboard in an area where the ambient atmosphere contains volatile or corrosive gas or vapors. If the panelboard is not going to be immediately installed, it must be stored in an area where it is not exposed to a corrosive atmosphere. If the panelboard is to be installed in a C3 or C4 zone exposed to coastal air or in a corrosive atmosphere, then a stainless board should be considered.

Ingress Protection
All MOD6+ panelboards come with predefined and tested IP ratings. The IP rating is marked on the panelboard labeling.

Important Notice: The installer must meet all AS/NZS 3000 section 1.7 requirements for the selection and installation of electrical equipment. The installer must ensure all fixings and cable intrusions meet the listed IP rating of the panelboard. Example: ensuring that the correct IP-rated cable glands are being used. When mounting all enclosures the fasteners and sealing around these fasteners must maintain the required IP rating. NHP offers an IP66 mounting sealing kit PN: CPPIP66 to assist with this.

Cable Gland Recommendations
Appropriate cable glands should be used for all panelboard cable entries. Where possible use the gland plates provided with the panelboard for cable entries. Remove the gland plates before slotting or cutting for cable entries to avoid ingress of swarf & other debris. If using large single-core cables use nonferrous gland plates to reduce the chance of eddy currents. Selection of the cable glands must not compromise the panelboard’s required IP rating. Follow the cable gland installation manufacturer instructions to ensure correct installation.

Accessibility
The installer shall install the panelboard according to AS/NZS 3000 section 2.10.2. The panelboard must be arranged to provide sufficient space for:

The initial installation
Replacement of individual items of control and protective devices
Accessibility for operation, testing, inspection, maintenance and repair

Warning: Consideration shall be given to provide a means of escape from the immediate vicinity of the panelboard in more than one direction, in case of an arcing fault occurring while work is in progress at the panelboard.

Operation

Once the panelboard is installed, wired correctly, and before the supply feeding the board is switched ON, the following start-up procedure should be followed:

Ensure all supplies feeding the board are isolated
The main switch or main incomer protection device and all protective devices internal to the panel board are OFF – MCBs or RCBOs
Switch ON the upstream supply breaker
Switch ON panelboard main switch or main incomer protection device
One by one switch ON the required outgoing circuits – MCBs or RCBOs

Modification and Repairs

The busbar and chassis for all Concept panelboards are designed to suit only NHP MCBs and RCBOs. If non-standard products are used the person modifying or repairing them will be responsible for re-verification to AS/NZS 61439. Modifications made to gland plates for cable entries are allowed (see section 4.3).

Important Notice: Failure to fit only NHP-approved circuit protective devices may void any warranty and prove to be dangerous. If the prospective fault level at this switchboard is greater than the MCB/RCBO fault rating, there must be suitable cascading with upstream protection.

Common in scope allowable modifications:

Emergency lighting kits
External lighting control kits
Surge protection
Concept-compatible door handles
Changing gland plates to nonferrous materials such as aluminum or brass
Fitting 160A or 250A Concept isolator
Fitting up to 200A MCCB
Allowable MCBs and RCBOs as stated below:

Board Type	Allowable MCBs and RCBOs (Model)

Testing and Maintenance

Applicable standards for testing and maintenance:

Standard	Description
AS/NZS 3760	Safety inspection and testing of electrical equipment
AS/NZS 3003	Electrical installations – Patient areas
AS/NZS 3019	Electrical installations – Periodic verification

MOD6+ panel boards should be inspected every 12 months and at least once within the initial 12-month warranty period. Electrical switchgear by its design and construction does not call for maintenance to ensure its function. Routine maintenance is however required to ensure continued safe and reliable operation. Panelboard routine maintenance should be dependent on the environment it is installed. More frequent maintenance is required for the following applications:

Environment	Frequent maintenance required
Harsh environment	Inspect structural integrity of enclosure, door seals, and

locking hardware
Vibration| Loose cable/power connections and potential physical damage due vibrations

Periodic Checklist

Check the torque of any fixing and fastenings, especially at terminals for conductors
Check for internal cleanliness (dust and foreign objects increase the possibility of short circuits and ark faults)
Check for obvious damage, defects, or modifications within the panelboard equipment and wiring insulation for discoloration that may indicate exposure to excessive heat, chemicals, or moisture.
Check the operation of circuit breakers
Check the condition of the paint finish, door gaskets, and enclosure for signs of damage
If applicable, check the operation of emergency and exit light testing circuits monthly and maintain them as per/NZS 2293.2

RCD testing
RCDs must be tested according to AS/NZS 3760 section 2.3.3.4 and AS/NZS 3003. A regular trip button test is required to ensure the correct operation of the RCD.
