Below you will find the technical charts for the following:

For calculating short circuits, we have sourced this information from a document found on the Schneider Electric website here.  However, if you don't have the time to download and browse through 35 pages, we have just the page here to help you. Calculating_short_circuit_current.pdf

Average full load motor currents table can be found in Schneider Electric's catalogue on page P25. Click here to view the Average_full_load_motor_currents.pdf

For general technical data, use the following link Technical_data.pdf downloaded for you from Schneider Electric's catalogue. You will find this page on P26. 

If these charts still don't answer your questions and you have access to a Schneider Electric Cataloge, flip to the technical references section in the back to find more charts and tables. Or, you can give us a call to talk to our experienced switchboard builder sparkies. We have designed and built all the switchboards shown throughout our website, so if you need to call on some switchboard experience or advice, feel free to contact us. 

Non-metallic outdoor switchboards in New Zealand get a bad rap for not being able to withstand the harsh U.V rays. But, when a switchboard is made with the right composites, and in the right configuration, an NZ U.V rated polycarbonate switchboard should see out at least 5 years of outdoor service. Read on to find out what else can affect the longevity of a polycarbonate enclosure.

Chemical resistance of thermoplastic enclosures is determined by its ability to sustain mechanical integrity while being exposed to specific chemicals. Obviously, temperature, chemical concentration, level of mechanical stress, and duration of exposure are variables that can greatly influence the performance of an enclosure in a particular application.

If you are looking for a versatile, expandable, waterproof, durable switchboard system, look no further than the Cubo P range. Designed around a series of bases with open sides, this system allows you to create numerous configurations to best suit your application. Read on to learn the nuances of Cubo P and perhaps get some ideas for that tricky job you haven’t quite figured out yet. Please give us a call if you need any help with designing a switchboard using Cubo P, or understanding how the parts work together. 

All thermoplastic enclosures we stock are manufactured using high-quality, halogen-free, and recyclable polycarbonate or ABS plastic. Although plastic is much lighter than steel, it has very high impact- resistance, in addition, any dents or bumps are not as noticeable in plastic as they would be with steel. Thermoplastic is also easier to machine, maintain, and alter than steel or aluminium enclosures with similar impact and chemical resistances.  

IK-rating is a number from IK00 to IK10, which tells how well products withstand impacts and hits. The higher the IK-rating is the better impact resistance it has. Typically, industrial grade enclosures require IK-rating from IK06 up to IK10.

IK ratings goes hand in hand with IP ratings of switchboards and, is a particularly important factor when it comes to outdoor switchboards or, switchboards in high traffic areas. While IP (ingress protection) measures the environmental protection that a product has from particles and liquids, IK ratings, as described above, measures the protection the item has from an object hitting it (let’s say, a hammer), at increasing weights and height. You need both high IP AND IK ratings to be sure that your switchboard will stand the test of time.
For more information, go to our IP & IK rated switchboards page.

For industrial enclosures, third party impact test conditions should be conducted both in -25C and +35 Celsius temperatures. This means that the product is suitable for both hot and cold climates. For plastic enclosures, the cold temperatures are more challenging as the material becomes more brittle. There are aging tests conducted for the enclosure to simulate environmental conditions and then the enclosure is targeted with impacts based on the expected IK-rating. After the targeted hits, the enclosure needs to function as it is designed to.

Despite the fact that the attached link below is for a lighting company brochure, the IP & IK metrics and measurements are the same across all industries. Scroll to page spread 15 to view the tables.
