As promised I said I would come back and update this and I am happy to say the hot pocket was yummy. I've had many more sense the original review and plan to keep enjoy more in the future...
Ohh yeah - the distribution blocks worked great also but I didn't eat those...

Great
I upgraded my old bus bar with this one as I upped my amperage, and it was now necessary to go with a larger one. It was very easy to replace the old one, as the form factor and holes lined up with the old one exactly.
This bus bar is high quality and can handle up to 250 amps through four 5/16 posts. There are also three screws for connecting low amperage devices allowing for a total of seven connections. That was exactly what I was needing. I now have piece of mind knowing that this bus bar will handle everything I can throw at it. No warming, secure and safe connections with protective covers for added safety.
This is marine quality for long lasting performance. It is top quality and I find it to be a terrific value for the price. I give this bus bar 5 stars.

Good fit, easy install, easy reconfigure
Use anti seize - just a very slight amount, on the threads.
If you have any concern for heat, test this. It has no rating showing. I'm running nearly 150 amps through this and so far see no heat buildups. The design would allow the busbar to pull out of the plastic if there were a fire, melting, etc. Mine is on a SOLAR PV - charger to 3 large batteries. I have fireproof material under the item. I will clamp the cables so then don't move if things melt. Wishing for a current and temperature rating.

Exactly what I needed
I had all kinds and colors of wires running to my battery in my UTV to support all the 12V accessories that are on it. I used these distribution blocks to organize and clean up the mess. Much better now after installing these strips. Instead of 4 or 5 wires running to each battery post I now have only 2 wires. All the connections now stay tight as well. Excellent quality product no need to hesitate on buying this item.

Easy, and works well
This was my second purchase. I liked the bus bars I bought the first time, so I bought them again. I used them in the construction of a full-capability portable amateur radio station, and opted for these over Anderson Power Pole buses. The bus bars are less expensive, and can handle 10 times the current of the Anderson products. As a result, they are safer. If for some reason, a dead short occurs, then with the 250 Amp capability, it's not likely these would be damaged.

Good basic High Amp connections for Power distribution.
Used for my Solar system setup.
4 3/8" terminals were perfect.
They feel loose until you tighten them.
Washers and lock-nuts included for each post.
I have a 24V 200A/ hr battery, 2 EPever BN-4215 charge controllers and a 4000W inverter.
All have a dedicatred post. I could double up the charge controllers if needed.

High quality, strong, built to last.
Very strong, easy to mount, small screws also included in mount base for add on devices like monitors, etc, plus covers to protect when open mounted. This was used to feed my solar inverter from my battery bank. It still allows me the option to add another future battery bank from the same terminials.

Excellent
I'm using two of these for a vehicle-based solar power installation. Great build quality, decent price.
In addition to the large lugs for high-current connections, the small screws are handy for low-power connections and eliminated the need for an additional bus-bar.

Heavy duty power distribution
Heavy well made block with stainless steel hardware.
Using it on a C3 Vette that's been updated with A/C, electric fans, small powered subwoofer and, Headlight relay.
Needed a way to get power and ground to everything from side terminal battery (pain on the ass). Mounted blocks in battery box with 1 lead off battery to feed each and all auxiliary feeds from each block, perfect
Question & Answer
Question :
Do you mean 250 amps per post or the entire buss bar?
Answer :
Each post is tied together with the contact plate, so the 250 amp rating is for the entire bus bar. Sorry for the confusion.
Question :
How do you connect this to the battery?
Answer :
You will need to purchase loop terminals and wire of sufficient size to handle the amperage. Most recently, I used these as part of a system which needed to be assembled and disassembled, quickly. Also, my system did not draw more then 25A; therefore, I used BUNKER INDUST 50A 6-10 Gauge Battery Quick Connect Disconnect Wire Harness Plug Kit, and large gauge wire, with loop terminals connected to the studs in the distribution block.
Question :
What size is stud ?
Answer :
3/8". We also have a 5/16" version.
Question :
do you need to ground the black bus bar if it’s screwed into plywood and not to metal?
Answer :
The body of the bus bar does not serve as the ground itself. You need to connect one of the posts of the black bus bar to your ground. Depending on your application, that could be a location like a bare metal spot on a frame rail or the negative post on a battery.
Question :
What is the amp rating?
Answer :
Maximum of 250 amps at 12 volts DC, per connection.
Question :
Is there any rating on how many amps each post can handle?
Answer :
Not that I have found. However - I am currently running 300amps through mine with no issues.
Question :
How hot does this brass block get when passing a continuous 250Amps thru it?
Answer :
I push 200a through it with no appreciable heating - use a temperature gun to check connections and components.
I would not push 250a through a bussbar rated to 250a... go bigger.
Question :
Is this designed for outdoor use exposed to weather?
Answer :
I wouldn't recommend it. All connections are very exposed.
Question :
They're rated to 48v - but could handle up to 55v, for example, so long as the max amps are not exceeded, right?
Answer :
I wouldn't hesitate to put 55v on it. The rating means it has been lab tested and proven safe at the test voltage. Could it handle 7 more volts than 48? I 'm sure it could - you just can't sue them if a problem happens.
Question :
Will each post accept 48v? Or is this a total 48v (4 posts x 12v)
Answer :
They are hooked together so if you put 12 volts in you get 12 volts on all 4 posts if you feed 48 volts you get 48 volts on all 4 posts. It is a buss bar.
