### ⭐⭐⭐⭐⭐ Quality and reliable product

### ⭐⭐⭐⭐⭐ Great

Great

### ⭐⭐⭐⭐ Nice big chunky busbar(s) with ANL fuse capability.
*by M***. on 25 February 2024*

I'll be using the red one on my campervan inverter, at the moment i'm running the power directly from 4x 200A resettable fuses, which is a bit naughty.I have a 3500w(7000w peak) inverter, which i'll limit to 3000w by using a 250A ANL fuse in this busbar and on the output, i've limited it to 10A (240v) to not drive the inverter to maximum.These are nice, robust and very large and should handle the power well, I like the fact they have 2 connectors either side of the fuse, making connections easier.I would have liked to have seen a pair of RED FUSED busbars instead of a red & black, you don't put a fuse on the negative/ground connection! It should have been a solid bar with 4 or 5 connectors.Even though it's black, I can still use the black one for (+) connections, I may spray it red or simply label it.I've give these 4 stars; the quality is good, but they should have been 2 red fused busbars or the black should have been a solid, then the price would be worthwhile.
