AMOMD Connecting Blocks Editorial Review
The AMOMD 2 PCS bus bar box is a heavy-duty module design battery power distribution junction terminal block. Customers can choose to purchase one for around $37 or both colors (red and black) for $75. It can handle 45 amps of 120 VAC, and 1/0 ring terminals fit side by side in the bus bars. One customer was able to use them as power distribution blocks on a 2000w RMS car audio system powered by a 350 amp alternator and 2 AGM batteries with no issues. The product has received positive reviews for being well-made, heavy-duty, and working as expected for solar and sound system installations.
