Glarks 70Pcs(5Sets) Terminal Block Set, 5Pcs 3 Positions 600V 15A Dual Row Screw Terminals Strip + 5Pcs Pre-Insulated Barrier Strips + 60Pcs Insulated Fork Wire Connector (3P+Fork Connector)

I used these in a DIY AT computer power supply converted to a bench supply. The color codes meant I could dedicate them to distinct output voltages (yellow for 12 volts, red for 5 volts, etc.). Works great for this application.

The variety pack of Glarks 15Amp 600v terminal blocks are alright, but the typical hardware used with 15amp wiring pushes the mechanical limits of these: screw thread strength, plastic case strength, and connection area of the terminals/spades. They're not flimsy, but they are not durable either. They're excellent for lower amperage applications where wires are thinner and more pliable, and the 15 amp rating seems generous.The spade connectors have narrower prongs than seems appropriate for 15 amps, but they are functional and can be put on with a with a basic crimper/wire stripper. They are slightly below average quality, imo.If you're using stiff or 14 ga+ wire, need it for rough duty, or want to run 11+amps, I suggest you look to a 20 amp model, for safety. Otherwise, this is a solid buy.

This review is for the Glarks 70 piece TB1503 terminal block kit. There were no problems with the order or shipping so on to use of the kit.I was very pleased to find this kit which includes five 15amp rated terminal blocks, 60 various forked crimp terminals, and five three position shorting bars to combine adjacent positions.Each terminal block position can handle two crimp terminals per screw position. Trying to fit a third ends up with minimal screw threads engaged and pulling/moving the wiring may allow the screw to come out. It is best to mount the lower terminal with the crimp part of the wire facing down while the upper terminal would have the crimp part facing up. This keeps the thickness of the forks to a minimum. When you need more than what you can fit in one position is where the shorting bars can help by extending the number of terminal positions. A word to the wise is figure out how many wires you are going to need connected together and then determine how many positions will be needed. For example if you use the 3 position shorting bar then you will only be able to add 1 connection on top of each shorting bar position; but you will still have the six positions available on the opposite side for a total of 9 wire connections for one TB1503.One aspect I found disturbing with the kit is that you receive a quantity of 20 each 10-12ga, 14-16ga, and 18-20ga forked crimps. However, the “15” in the model number indicates the terminal block is rated for 15 amp circuits (also marked as such on the block cover). That means the 10-12 ga terminals should NOT be used with this terminal block. Ten gauge wire is rated for 30 amps and 12 gauge wire is rated for 20 amps – both exceed the rating of this product.My argument for dropping one star is you receive five terminal blocks which have 6 positions each for a total of 30 possible connections. Yet you only receive 20 each of the fork crimp terminals. I'd suggest the manufacturer delete the twenty 10-12ga crimp terminals in this kit and replace them with adding 10 more each to the other two sizes. Although if you are like me you'll need extra crimp terminals for most projects regardless.I ran into a problem as I was installing a TB1503 into a metal electrical enclosure. I was not able to use #8 pan head machine screws inserted from the back side of the enclosure. The round recessed mounting hole on the terminal block will not accept the nut. A #8 machine screw will work when installed from the top of the TB1503; but that puts the nut and extra screw threads on the back side of the enclosure (not helpful for surface mounting the enclosure). I had to drop to a #4 size screw/nut – much smaller than I'd like when I could have as many as twelve 14ga wires connected to the terminal block. In years past I was able to buy terminal blocks that had a hex shaped opening for the terminal block mounting screws. Those worked well with screws thru the back and the nut inside the terminal block or you could mount using small bolts/nuts.Overall the kit is very useful and well worth the price. I would certainly recommend it if you are going to start an electrical project with multiple wire connections.

Just as expected

Happy with item.

Good quality set. Has everything need to do easy installation

Worked just like it should. Not much else to say.

Nicely made. Doesn't look like it should carry more than eight amps. However, when would you carry that much current?
