Are there any other opinions?

What would you do in the case of the terminals on the battery, or PD board, or the main breaker?
Is it okay to leave the nut exposed so it can be serviced?

Or should it be somehow wrapped in electrical tape, or goobered in hot glue?

Or is there a more appropriate way of insulating this that allows it to be serviced?
