Technical responsibility
A design aid, not a certificate
EternaCAD helps you design, calculate, simulate and document. It does not replace the judgement of a qualified installer or engineer. Nor does it certify that an installation complies with the Spanish REBT, its ITC or any other standard.
The person who designs, builds, inspects and signs off the installation is responsible for it, and for the documentation delivered to the client or the authorities.
Calculations and proposals
Cable sizes, voltage drops, short circuits, selectivity and load estimates use simplified methods, IEC and UNE tables included in the program and typical curves, not those of each manufacturer.
Before accepting a calculation, check it against the current UNE tables, the manufacturer data and the real conditions of the installation.
Automatic proposals are indicative: home wizard cable sizes, panel wiring, enclosure and labels.
Simulation
The simulation shows the circuit logic and an approximate behaviour of motors, protections, pneumatics and PLCs. It does not reproduce every real phenomenon and is not a test of the installation.
The inspections on the measurement sheet are the ones you take with your instrument. EternaCAD only compares them with the usual limits.
