SHEET METAL CONSTRUCTION TYPE Method of construction depends on location budget and delivery time. Other than CUBIC, IP ratings are IP 55 when vented IP66 if not vented. Other than flooding, IP55 is suitable for all outside extreme full weather conditions. For all custom manufacture methods pans and escutcheons are aluminium. Custom fabricated 3.0mm MARINE GRADE ALUMINIUM – Used if exposed to full weather most commonly used and offers best value and equal lifespan to other custom fabricated methods. Custom fabricated 1.6 / 2.0mm STAINLESS STEEL – Used if exposed to full weather but can cost up to approx. 30% extra. Manufacturing a SS custom enclosure provides absolutely no benefits whatsoever over Custom Aluminium. Outer cubicle and doors are usually 2.0mm and the inner barriers are 1.6mm. Suggest Pans and escutcheons to be Aluminium. Custom fabricated 2.0mm ZINC ANNEAL STEEL – Used if exposed to partial weather. Requires powder coating to prevent rusting. Any scratch will eventually cause rusting over time if in full weather. Rarely used minimal cost savings over Aluminium. CUBIC modular (bolt together) system – Used for indoor applications only. Provides quick, cost effective construction. Fully type tested system. Panels and frames already powder coated Grey as standard. IP43. Mounting pans not powder coated. Powder coat external panels are available in Orange. Sometimes delayed delivery on Orange Panels depending on stock levels. NHP Prefabricated Enclosures – Powder coated steel (ELDON) if exposed to partial weather (as per zinc anneal). Enclosures are limited by set dimensions. NHP Prefabricated Enclosures - Stainless Steel (ZANARDO) if exposed to full weather. Ideal for small single control panels. Enclosures are limited by set dimensions. B&R Monarch IP Powder Coated steel enclosure – as per prefabricated enclosures but all internals are of a modular bolt together system. Provides a high quality, very quick but slightly more expensive construction method. Hinged meter panels, inner escutcheons, barriers and powder coated pans are all available. Enclosures are limited by set dimensions. B&R Monarch IP Stainless Steel stainless steel enclosure - as per above B&R3M & B&R3MECB - Off the shelf powder coated sheet steel metering panels from the electrical wholesalers.

DOOR LOCKS AND EXTERNAL HARDWARE DOOR LOCKS - Metering sections are always pad lockable. Other sections are either pad lockable or 92268 key lock. EXTERNAL DOOR HARDWARE - Chrome Plate or Stainless Steel. Stainless steel adds extra costs. INTERNAL ESCUTCHEON HARDWARE - Always chrome plated. Can use 1/4 turn catches slotted, square or triangle that require a tool to open, or lockable T handles.

WEATHER SHADE - Protects board from the elements such as rain and sun. Sun hood and false plates can be selected together. SUNHOOD – Constructed from the same material as the cubicle and is attached to the top of the board GALVANISED SOLAR SHADE – Constructed from galvanised steel, & expanded mesh with purlins and a colour bond roof similar to a “Bus Stop” shelter. Requires a larger concrete slab for fixing of frame around the board. FALSE PLATES – Constructed from the same material as the board and is attached to the vertical board panels providing an air gap between the outer cubicle panels to reduce heat build-up inside the board. BUILDING - Board is inside a building and does not require a weather shade

  • WEATHER SHADE

  • IF A GALVANISED SHELTER IS REQUIRED HAVE CUTOUTS FOR VENT FANS OR GENERATOR INLET SOCKETS BEEN CONSIDERED

  • HAVE THE SHELTER CUTOUTS BEEN POSITIONED ACCURATELY AND LINED UP WITH THE SWITCHBOARD BEFORE GALVANISING

  • IS THE SLAB AROUND THE SWITCHBOARD SIZED ADEQUATELY TO ACCOMMODATE THE SHELTER

POWDER COATING AND CUBICLE SURFACE FINISH MAIN CUBICLE - Improves external appearance. Powder coated colour as required, sanded finish or bare finish Usually selected on on Custom Aluminium, however not essential. Not essential or necessary on Stainless Steel. Essential on Zinc Anneal. Refer further to sheet metal construction If powder coating is selected, the internal and external main cubicle surfaces will be the same colour. If a sanded finish is selected only the external main cubicle surfaces will be sanded. Fabrication weld marks may be more visible. Due to the labour and materials required to sand the cubicle surface, there is no cost savings for a sanded finish over a powder coated finish. If a bare finish is selected the outer surface will be as is when it leaves the sheet metal shop, and all buff marks on the outer surface will be visible from where the internal welds are. If the external cubicle surface appearance is not critical there are cost savings involved in choosing this over a powder coated or sanded finish. Chose Colour M-Magnolia / WG -Wilderness Green / GW- Gloss White / EO - Electric Orange / LG Light Grey / S Sanded / B Bare. M & GW are the most commonly selected. Cost and delivery time will increase with powder coating and sanded finish ESCUTCHEONS - Usually done on all boards, even brushed finish. Colour is GW CONTROL GEAR MOUNTING PANS - Not necessary but does improve appearance. Colour is GW

SUPPLY AUTHORITY METERING - How is the installation to be metered. Unless there is a previous job with an approved metering arrangement, reference should be made to the ERGON Electricity Connection and Metering Manual (ECCM). Reference is usually required for CT metered boards and multiple customer arrangements, as these can sometimes involve a "non standard" arrangement of the meters. When designing these types of boards, approval from ERGON is required to confirm the design is correct. Single customer direct connect metered boards are usually straight forward and do not require any approval by ERGON. However compliance with the ECCM on direct connect metered boards is still required. TYPE OF SUPPLY AUTHORITY METERING - Direct Connect Metering for loads up to 100A. Current Transformer Metering 200/5 for loads up to 350A, or 800/5 for loads up to 1400A. LOCATION OF METERS - Cubicle in Switchboard, Remote Meter Cubicle, Remote Meter and CT Cubicle, Remote Main Switchboard REMOTE CUBICLE CONSTRUCTION MATERIAL - Refer to SHEET METAL CONSTRUCTION for section options. NHP prefabricated is not an option for this. METER NUMBER - Assists ERGON with existing installations if the meter numbers are provided.

If the main switch is not a circuit breaker (i.e. it is a load break switch), make note of the kA rating of the downstream sub circuits, as these will be circuit breakers. If the installation is new advise of the required kA rating.

MOTOR STARTING AND CONTROL EQUIPMENT - Describe the motor details and starting method and what selectors and indicators are required. If there is a dual pump configuration with CIRCUIT NAME - As shown the engraved label MOTOR MAKE, MODEL NUMBER, MOTOR kW AND AMPS RATING- As shown on the motor nameplate or data sheet AUTO CONTROL STARTING METHOD - How does the motor start in Automatic mode - Level, Timer, Time clock MOTOR STARTING METHOD - Choose from the most commonly used methods: DIrect On Line (DOL) uses a contactor and electronic overload. Usually used on motors up to approx 5.5kW. Above this rating it is ideal to consider using an alternative starting method. Soft Starter (SS) din mounted starters occupy less space and provide basic ramp up and down time. Usually used on motors up to approx 15kW although some models can be used on higher rated motors. Most din mounted soft starters have no overload protection built in so these are used with a contactor and overload. May be required on motors above 2.4kW if in remote locations due to power supply restrictions. Soft Starters (SS) Larger framed starters offer more customised parameter settings for larger motors. Overload protection is built into the starter. An LCD screen displays motor details and parameters. Can be used on motors from approx 4kW and above depending on the lowest overload parameter setting within the starter. Variable Speed Drive (VSD) used on motors from as low as 0.37kW. Method of speed control must be stated. Star Delta starting is rarely used. Auto Transformer starting is rarely used MOTOR PROTECTION - Depending on the motor make there can be multiple sensors that protect the motor. Certain motors may require a specific motor protection relay. Refer to the manufacturers data sheets. Microtherms, Thermistors, MiniCAS, MAS711, Seal Fail, Low Flow, Undercurrent.
