Will the standard Zig-Zag connection shown in the Acme General Catalog serve as an I-Trap™?

No. The I-Trap™ is specifically designed to reduce high neutral currents.


To eliminate the problem of overheated neutral conductors, why not increase the size of the neutral?

First, increasing the neutral size does not eliminate the harmonic problem – they are still present in the system and may cause transformer overheating and possibly failure.

Second, installation of a new neutral conductor in long runs may be difficult and cost prohibitive when compared to the cost of installing an I-Trap™ unit.
