Jamgoer 300A Bus Bar Heavy-Duty Module Design Power Distribution Block 12V 24V 48V DC Busbar Box with 4X M10(3/8) Terminal Studs for Battery Marine Automotive RV Car Truck (Red&Black)

High quality

I was skeptical that these terminal blocks would be flimsy/cheap plastic and/or the metal block and nut would be of low grade....

No High voltage high current concerns with this product. Built solid. Bought another set.

Nice, sturdy bar. Does exactly what its supposed to. Easy to configure for different routing options.

Works great nice and solid.

Excellent quality. Works great.

I liked the terminal cover, couldnt find another style in this amp rating with as nice of a cover. The cons are the bus bar is made of brass, instead of copper, and I would not mount this to metal, as the base plate is thin, and there are screw coming from the backside to mount the bus bar to the base plate. Very little distance from the mounting screws to the mounting surface. Ill be mounting it on a non conductive surface

Great value for my solar install.

Fairly fast shipping (from China!) with decent tracking. I was amazed by the quality of this product. Not the cheap junk I expected. The plastic was thick, reinforced, and strong, the bus bar was very thick and the studs seem like quality stainless with lock washer. The cut-outs for the cables are well defined yet strong and ideally cut out using a rotary tool like a Dremel. The mounting studs for the bus bar are counter-sunk into the plastic housing and covered with a foam pad. Even if the bar heats up and melts the foam it shouldnt make contact with any metal the plastic housing is mounted to; a nice bit of safe engineering. Highly recommended.

This unit is very Stout and lovely. It easily handled 150 amps of raw power. All hail the jamgoer up 300 amp bus bar.
