IEC 60364 Table 48A

Former Community Member over 3 years ago

Does anyone know where I can find table 48A? I am reading of its existence, but don't know where to find it.

There's also a trade-off between conductor size and cost.

Indeed. The simplest (but most expensive) solution would simply to make the c.p.c.s (all the way back to the transformer) 5x the size of the line conductors - that way touch voltages remain below 50V even during a fault (or 10x and 25V if you prefer).

Thats just one of two other factors. Speed and transformer output drop also play a role in protection.
