Wondering if you guys have any thoughts or opinions regarding flash barriers on circuit breakers.
I have noticed over the past couple of years that more and more DB manufacturers have stopped supplying flash barriers when it comes to MCCB's rated over 100A.
After much discussion with them the consensus is that when the DB manufacturers order the circuit breakers they don't come with the relevant flash barriers.
Some say there is a minimum distance before flash barriers become compulsory but I can't seem to find anything on this.
Your thoughts????
