Thanks to all. I have made the recommended changes.

The questions look good to me. One picky point is that the standard does not literally require a

particular technology. However, designing and manufacturing a transformer to meet a standard may

have certain limitation such as a particular grade of steel or core construction; particularly when costs

are factored in. I support Ric hard’s and Andrew’s recommendations for improving the survey to allow

the interviewee to discuss the construction approach.

Thanks,

John

All,

Attached is the list of questions for small manufacturers.

### 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% 98.93%

Design Line 8 (DL 8) 3 ph, 225 - 1000 kVA 98.00% 98.47% 99.02% 99.25% 99.32% 99.44%
