Do I need a positive and negative busbar?
The traditional way of installing a DC system was to connect the ends of each circuit directly to the battery bank’s positive terminal (or, more likely, the battery cut-off switch) and the Earth point. Even if you decide to use busbars, you don’t need to use both a negative and a positive busbar.
What is HT and LT breakers?
It is rated in terms of maximum current carrying capacity, maximum voltage, number of poles, frequency, maximum interrupting capacity, etc. There are different types of circuit breakers that are used for circuit switching mechanisms under the low tension (LT) and high tension (HT).
What size drive breaker bar do I need for AutoGuide?
After a lot of research, we chose Neiko’s 1/2″ drive breaker bar to use in the AutoGuide garage.
