Rob and Richard:

I agree with the modification suggested for quest ion 7. A potential "future" standard would not "require" mitering since wound cores are an option to reac h the targeted efficiency levels. Given the options to make more efficient transformers, perhaps the question should be re-phrased to be more open-ended. Perhaps something like "In the ev ent the next efficiency standard cannot be met by butt-lap designs, how w ould you expect to respond?

Also, in addition to sourcing the cores another option for small ma nufacturers might be to source

the finished transformer. I realize this will not be an attractive option if covered transformers are a big piece of a particular company's business, bu t for those for which covered transformers are a small piece of their overall operations and revenue, this may be a viable option. My understanding is that ther e is already some re-labeling of fini shed transformers in parts of the

market.

Thanks for the chance of offer input.

These look good to me. Andrew and John Caskey : do these questions cover the issues you would need resolved to inform your vote?

One very minor tweak: Rob Greeson has indicat ed that FedPac would probably prefer wound cores to mitered at EL 3 and above for larger volume production as mitering can be slow. So you might want to consider tweaking Q7 to read "favored mitering or wo und cores" instead of "required mitering."

Mike and team,

As you may recall, we all agreed last Friday to send out and/or call the small manus in the low voltage space to pose a series of questions we di scussed in meeting generally. The plan was to draft a brief questionnaire and circulate that questionnaire internally before sending out/calling

so that stakeholders could make sure their key questions are addressed.

I realize everyone is stretched for time at present, so in the interests of expediting process I offer the following queries that I believe more or le ss capture the kinds of things we talked about needing to find out. This draft is offered just to get the discussion going. I have no pride of authorship and I'm sure your team can refine thes e questions to make them more artful, precise,

relevant.

Main thing is we need to get the questionnaire finalized and pres ented to the companies so we can get answers ASAP.

I know Andrew DeLaski and John Caskey expre ssed an interest in getting these sorts of questions answered, so I will invite them to weigh in as well with any suggested changes. If we don't need all this information, by all means let's eliminate any ques tions that aren't needed.

Once the questions are settled, we need to disc uss manner and timeframe for presenting them -- through written questionnai re or phone calls.Best,

Richard

Draft questions

1. What is your total annual sales volume, and total employment?

2. What is your total annual sales of transformers?

3. What volume of sales (by $ and/or MvA) are covered products [Navigant to supply definition of what that is]?

4. What proportion are exempt products [Nav igant to supply list of exemptions]?

5. Do you ship low-voltage transformers that ex ceed the current efficiency standard of 98% efficiency (in the case of Design Line 7, which are 3 phase transformers from 15-150 kVA) or 98.60% efficiency (for Design Line 8 which are 3ph, 225-1000 kVA)? If so, what efficiency levels do they reach and what is the volume of sales at each higher level?

6. Do you outsource any of your cores for covered products? If so, what proportion of cores

are outsourced?

7. If you make your cores internally, pl ease answer the following questions:

o what core design do you manufactur e (e.g. butt-lapped, step-lapped)

o what core steels do you employ? If more th an one, please indicate the percentage

mix of steels.

o Do you have utilize mitering techniques currently?

o Do you make wound cores currently?

o If hypothetically the industry were to m ove to a higher efficiency standard for low-voltage transformers at which efficien cy level (EL) (see table below) would you find it expedient to convert to m itering or wound core designs (please specify) and what would the total an d per unit costs of conversion be?

Current

Standard EL 1 EL 2 EL 3 EL 4 EL 5 Design Line 7 (DL7) 3ph, 15-225 kVA 98.00% 98.47% 98.60% 98.60% 98.80% 98. Design Line 8 (DL 8) 3 ph, 225 - 1000 kVA 98.00% 98.47% 99.02% 99.25% 99.32% 99.
