Pretty much what the title says, but when we put the 20A and 30A circuit breakers on the PDP, there’s a small gap between the board and the breakers that is not present with the 40A circuit breakers. This occurs on all the ports on all our PDPs, so it is unlikely that it is caused by a metal shaving or whatever stuck in the port. We’re pretty sure it’s ok, but we just want to make sure that this is normal/intended.
In my experience, push harder, they will go in. :rolleyes:
Absolutely. They’ll go in, and you want them to go in all the way. That is WAY too much of a gap. Something could very easily fall onto the board and short those out.
It could arguably be a violation of R42 “Each electrical terminal on the ROBOT battery, main breaker, and their connections (lugs, stripped wire ends, etc.) to the wire must be fully insulated at all times.”
One side of the breaker is directly connected to the Main Breaker (via the PDP), and thus part of “their connections”, and must be fully insulated at all times.
During inspections I ask teams to push breakers all the way in, for exactly this reason. I think many other RIs do the same. Every LRI have talked to about this agrees.
Except the breaker are neither a battery, main breaker, or their connections. :]They are a specified COTs device plugging into another specified COTs device. If they are fully inserted and have a gap: so be it. The key is to to be sure they are fully inserted
As long as they are fully inserted and do not fall out you are OK. I have found some have lightly different blades than others. However, I recommend you check with a bright light to be sure there isn’t something blocking the terminals.
