Multi ground wire splice

Is there an outdoor rated round bar that I can mount in a pvc enclosure ?

It shoulnd't need to be mounted - doing so with a metal enclosure is a method of bonding to the enclosure. But I guess you still can mount it if you wanted.
 
Is a ground bar required to be rated for damp/wet locations in an outdoor junction box?
 
The specs say 6 #10 or #12.

IMO, it will work especially if the wires are pretwisted.

I need to correct myself.

The specs range is from 4 #14 to 6 #10. Not maximum 5#12s.

If I have done this correctly:

area of #10 is 10380 so 6 #10s = 62280 circular mils
area of #12 is 6530 so 8 #12s = 52240 circular mils
 
Looking for something better than a Buchanan splice filled with Noalox, which isn't listed but which I personally trust a whole lot more than a wirenut with slippery goop inside.



I don't know of any wire nut that is listed for more than five conductors.

The red bcaps top out at 5 #12's and the 2011 buchanan crimps can take up to 7 #12's- thought about mentioning those earlier but as Jaggedben pointed out, not 100% on the legality of the goop and the listing of those products....

OTOH, depending on the circumstances, it may not even be necessary to use any type of sealant/anti cor. Lots of panels are outside, we don't do that to the joints in them, just plain old wirenuts, and no problems.

Other than underground splicing, show me where it says that splices must be waterproof. Connectors, if used, don't even have to be listed, just identified for the use.
 
It would be legal to twist all 8 conductors together in a manner that provides all the mechanical integrity necessary for a good connection and then solder them. If the EGC's are bare, nothing more would be required, not even tape.

I agree about the un-insulated part but what about 250.8(B)?

250.8 Connection of Grounding and Bonding Equipment.(A) Permitted Methods. Equipment grounding conduc-
tors, grounding electrode conductors, and bonding jumpers
shall be connected by one or more of the following means:
(1) Listed pressure connectors
(2) Terminal bars
(3) Pressure connectors listed as grounding and bonding
equipment
(4) Exothermic welding process
(5) Machine screw-type fasteners that engage not less than
two threads or are secured with a nut
(6) Thread-forming machine screws that engage not less
than two threads in the enclosure
(7) Connections that are part of a listed assembly
(8) Other listed means
(B) Methods Not Permitted. Connection devices or fit-
tings that depend solely on solder shall not be used.
 
My take on that is that for splicing any other conductor a mechanical connection followed by solder is OK, but for the purpose of grounding and bonding the list is explicit and the only open ended option is for "other listed means".
That the CMP chooses to add an explicit prohibition of something that does not appear in the list should not be taken to imply that solder with a mechanical connection not in the list would be OK.

So, for instance, a pressure connector plus soldering is acceptable but twisting plus soldering is not.

That is a good point, but is a splice considered 'equipment'? I would think if it were, that would be mentioned in the definition. I don't consider wiring to be equipment, and I don't consider splices to be, either.

250.8 Connection of Grounding and Bonding Equipment.

Where would wire nuts fall into the accepted means of 250.8? The only place I could see would be the green wire nuts with the pigtail listed for connecting the grounding conductors to the box.

Do you guys enjoy trying to fit that many solid #12's under a wirenut? I don't. Your debate is pointless. I'd use a ground bar kit or 10 port wago and be done with it. Changes to the wiring are a lot easier as well with either of those two.

After using multi port connectors (I used Ideal) for more than 6 solid #12's, I agree with you about the 'Wago's. Not only are they much easier to work with, I found them to be superior to wirenuts because they allow for movement of the conductors without compromising the connection, which is great when you go to stuff them back into the box. I won't use a wire nut for more than 5 wires any more, it's push on connectors for those.

Combination of solid or stranded, when they are pre-twisted together the blue wire nuts work great. If they are all solids no pre twisting is required, the blue wire not does the twisting for you. Assuming you have removed proper insulation.

What do you do when you have three #8s to connect together?
