Can we have cascading between NT (H1/H2) or NW (H1/H2/H3) ?

Unfortunately we do not have cascading tables for the NT (H1/H2) or NW (H1/H2/H3). Cascading is the use of the current limiting capacity of circuit breakers at a given point to permit installation of lower-rated and therefore lower-cost circuit breakers downstream. So we need current-limiting circuit breakers (ex: Masterpact NT L1, Compact NS, Compact NSX) to provide cascading. The Masterpact NT/NW (H1/H2/H3) ACBs are not current-limiting circuit breakers, while the Masterpact NW L1 is a current Limiting breaker.
