When installing bus bars, adhering to proper safety measures is crucial !

  1. Power Down for Safety: Always disconnect the power supply before installing or servicing bus bars to avoid the risk of electric shock.
  2. Insulated Tools: Use insulated tools for installation to minimize the chance of electric shock.
  3. Compatibility Check: Ensure the wires and bus bars match in specifications, including voltage and current capacity.
  4. Secure Connections: Make sure all wires are connected correctly to prevent short circuits or poor contacts. All connections should be firm and with no exposed wires.
  5. Avoid Overloading: Never exceed the maximum current capacity of the bus bar to prevent overheating or fire hazards.
  6. Regular Inspections: Routinely inspect the connections and overall condition of the bus bar to promptly identify and repair any loose or damaged components.

I ordered this for running lights on my farm tractor and here are my thoughts:First out of the box the plastic housing is rough, and the copper??? is showing signs of rust??It is magnetic. This can be a good thing, especially in my operation. It will work for its intended use. The price was okay and it has standard 3/8" ring terminals. Because it is magnetic what type of metal are they using under the plated copper? Because new out-of-the-box it has rust, I am wondering in using it in the open exposed to the elements as I am, if it will hold up without rusting fast. Only time will tell.

These are good quality terminals. The nylon insulator is thick and solid. The bus bar is thick and sturdy. The screw terminals and posts are sturdy and tighten securely.

This is a pair of bus bars, one red and one black. Each one has four posts. I have installed these on my DIY solar battery charge system. The mounting was pretty easy and installation of the cables was too. I don't run anywhere near the current rating of 250Amps, but these look beefy enough to handle it. When I expand my system past the 4 posts I have, I will reorder a set of these.
