Questions about this product

Can I use this bus bar in a hot engine bay to run a heavy-duty winch?
Yes, it handles up to 400 amps of continuous current and tolerates temperatures up to 105°C. This makes it perfect for high-draw gear under the hood of your off-road rig. Just ensure your total continuous load does not exceed the 400-amp limit.
Is this distribution block waterproof and safe for open boat engine compartments?
This block has an IP20 rating, which means it lacks protection against water ingress. While the copper is tin-plated to resist corrosion, you must mount it in a dry area. Do not expose it directly to rain, road spray, or bilge water.
What size ring terminals do I need, and how tight should I fasten the nuts?
You should use electrical ring terminals designed for 5/16-inch or M8 studs. When tightening the nuts, use a torque wrench to set them between 15 and 20 pound-inches. Going tighter than that can strip the threads or damage the flame-retardant nylon base.
