Cablesizer BETA v1.0

Cablesizer is a free online tool for sizing low voltage, insulated electrical cables. But from now on it is also available as the android application. Sizing has been performed according to the following standards:

* NFPA 70, National Electrical Code (NEC), 2011

* IEC 60364-5-52, Low voltage electrical installations - Part 5-52: Selection and erection of electrical equipment - Wiring Systems, 2009

Cable sizing should be easy and it should be automated. It is a well defined task and for most common scenarios, there should be no reason to do it manually by hand, or have to rely on integrated power systems analysis packages like ETAP, PTW, etc. These appear to be two extremes, but unfortunately most practicing electrical engineers have to choose between them because there is no a third option.
So with Cablesizer, we wanted to make an automated cable sizing tool that is both easy to use and completely transparent. You do not need any logins or password; just fire up Cablesizer and you can start sizing right away. More importantly, all the reports generated by Cablesizer include references to the relevant clauses in the standards, as well as the equations that are used to calculate the results. So Cablesizer is not a black box - you can take the results and check it independently against the standards.
But remember that Cablesizer is just a tool and the old adage applies - garbage in = garbage out. Therefore you need to at least know something about the fundamentals of cable sizing. To help you, take a look at our tutorial pages on the Cableiszer webpage www.cablesizer.com, in particular the principles of cable sizing page, or alternatively get a copy of the latest NEC or IEC standards.

This is the free BETA version which is applicable only for the NEC low voltage cable sizing (up to 2000 Volts).
