We are getting kickback from some AHJs in regards to 230.46. Has anyone found a product that is "suitable for use on the line side of the service equipment or equivalent"

We try to avoid polaris blocks for some reason that no one will tell me...
Any ideas?

Sorry, I should have clarified here. I'm more so looking for piercing or pressure connectors for line side taps. Something like the B-Tap Insulation Piercing Connectors, which is what our client was using before these rejections.

I'm not very well versed in these type of components because I only design, and don't install, so if I am wrong on something let me know!

See here:

See last post for possible progress from a manufacturer.
See post #4 for a link to earlier thread, plus ranting about how this rule got adopted and further background.

You may have to settle for listed power distribution blocks like augie is suggesting because apparently there is actually a history of UL having standards for those. Whereas for the type of connector you want the CMP is forcing UL to come up with new standards and last we heard they haven't yet.

Good luck. Let us know if you find out anything good.

Those Buchanon Btaps are listed and meet the requirements of 230.46
Could you send some documentation? I have gotten rejections like this:

I found this sheet from their installation manual that show it as listed for use on the line side of service equipment but these AHJs still say this in response.

I am contacting Ideal/Buchanen about it to see if they can help with this. Its super frustrating that there is nothing that would work with this requirement available right now.

Thank you guys for the help!

Pray tell what could they do to a connector to make it suitable for line side connection. I bet almost all connectors are safe however it may be a case of not being tested.

I bet @don_resqcapt19 knows what the difference would be.

That's why this is so stupid. Any connector was allowed for 100 years and the CMP took this action not based on any incidents that occured in the field. So now UL has to develop a test to show that the connectors prevent incidents that to our knowledge have never happened. (Perhaps something bad happened somewhere at some time, but without something known to refer to then how UL know precisely what the CMP wants.)

The reason they're not tested is no fault of the manufacturers. It's because the test doesn't exist. It has not been defined.

(If this info is finally out-of-date I'm happy to be corrected.)

@JimmysLimeade

There is also 90.4 paragraph 3. If you can get UL to confirm to you that the standard does not exist and show that to the AHJ to prove you cannot possibly comply, that might be your best bet.

Doubtful that I can get UL to give a statement like that, but I can try.

Any bets some one on the CMP works for a manuf of connectors??
I wouldn't be surprised, I guess we will have to see what comes out haha

This is screwing over the connector manufacturers, who will have to pay for new testing on existing products and can't sell their product in the meantime. So that's probably not what's going on here. This does not involve someone trying to get their new technology made into a code requirement, because as Dennis pointed out the existing products are probably fine and will pass the tests.

I heard back from Ideal/Buchanen and this is what they said: image_2023-08-03_104208151.png
Guess we will see if they can get listed in the next few months

Perhaps not on the CMP but you can bet that there are connector manufacturers on the Standard Making Panel.
I certainly hope manufacturers are involved in writing standards. I hate when someone specifies something that can not be built.

The concern is the high physical forces that will occur from the magnetic field with a high current fault. For all practical purposes there is no overcurrent protection for the service conductors.

The standards technical committees are set up much like the NFPA code making panels with members from various different interest groups. Both the UL committees and the code making panels have manufacturer representives. In both cases no one interest group can have more than 1/3 of the total membership and a 2/3s majority is required to pass anything.

The most recent version of UL 486A/486B has an Annex H for the line side connectors. I believe that was issued late last month.
