Default I would like to ask a real higher-up engineer a question

Can someone please pass a question to an engineer at Milbank, some familiar with the code, listings, and design of the meter pans?

Dear Rick & Cathy Holbrook
My name is Steve , I'm a Vermont electrician with a question about Milbank meters and/or enclosures I'm hoping you can help me with.

It would appear there is a dispute in just what the 1/4" knockouts on the bottom of your meters are really for

Some say it's for the GEC (Grounding Electrode conductor)* , usually a bare #6 or #4 copper wire to simply run through

However, we are finding this is not to code, the* NEC passage(s) below being applicable

Can you unfuzz me please? Thank you for your time

Hi Steve,
The ¼” KO’s are for water drainage only.
I believe this to be false. With all due respect to Mr. Rick Holbrook, it makes no sense for a 3R rated meter pan to require a knockout to be opened to drain water out. The meter pan comes arranged to drain from the factory with small weeping holes/slots.

Can someone please pass this up to an engineer who can give a definitive answer on the purpose of these smaller holes?

Here is an example (bottom right hand corner of the enclosure) of a factory weeping hole in outdoor enclosures, giving it it's 3R rating:

Those rear holes along with the slots in the front allow water to drain.

From the engineering department: "We have corner notches in the bottoms to drain water. The 1/4" KO is for the grounding wire."

Does that answer everyone's question? Let me know!

Thank you Marissa, I really appreciate it.

Can one of you gentlemen please post this at Mike Holt’s forum letting them know that now both Square D and Milbank specify the 1/4” hole or 5/16” hole is for the grounding electrode conductor please. Thanks.

Mike your POCO will usually spec what meter pans they accept. The local suppliers are going to stock whatever that market will require.

Pretty rare for us to even use a meter pan. We hang meter/mains usually and those are set to USERAC or some letters like that. Alternately , for larger services, we can mount a CT can and a meter pan for a checking meter, then a Service disconnecting /overcurrent protection , and then the panels remote if we like. That's about the only time I have hung a meter pan here , that and tenant check metering for commercial sub spaces.


I remember wholesale houses stocking Milbank items way long ago like 70's .
Except for this forum, I would have assumed they went the way of the Challenger during the buyout frenzy.

Saying EUSERC around here is like sending up a telsa bat signal.

So, telsa, since you won't dare step into the GEC thread, I will ask here...

You tried to substantiate the requirement to bond the GEC to a panel as it enters by saying that the existence of the Kenny clamp as a product being sold means that it had to be used, or else it wouldn't be available to buy. Those were your words, I can quote them here if you like.

So, using that logic, the fact that 2 of the biggest manufacturers say that the hole in their panel/pan is for the GEC to pass thru without being bonded, that would mean that it's OK, right?
