Electrical Material Supplies - Question & Answers Q1: Junction Box, NEMA 4X, Screw Cover, PVC: junction box pvc size A1: PVC: 12" x 12" x 6": see photo below
Q2: 225 kVA 480 VAC primary 120/208 VAC secondary XFMR - Equivalent of attachment: XFMR indoor/outdoor?
A2: outdoor (NEMA 3R) transformer
Q3: 600A 120/208V 3 phase NEMA 3R distribution panel board w/ main breaker: 600A main breaker doesn’t exist, I have quoted a main lug A3: Main Lug will work - but it will need to be double lugged Q3.1: Transformer does not include lugs, will the AU-600 be used for the transformer? If not I will need another list. Sorry there are other lugs on the order as well, KA29U, I assume they will be used for the transformer.
A3.1: See line item 49, Double Barrel Mechanical Lug (600 kcmil - 2 AWG). Match properties of item in link provided.
Q3.2: 600a panel will be at least 30 space, what amperage they want for the main breaker?
A3.2: Follow specs in PDF – 600 Amp Panel Board.
Q4: 300 A dual element fuses: 3-100 amp fuses or 3-300 amp fuses A4: (3) 300 A fuses
Q5: 600 AMP breaker with dual tapes: 600 amp breaker with dual tapes, need more clarification A5: 3 pole 600 amp breaker that has double lugs
| Q5.1: will be a breaker enclosure, open breaker, aic rating? |
| A5.1: Follow specs in PDF – 600 Amp Panel Board. |
Q6: 600 AMP breaker with dual tapes? As per one of our suppliers:
Unfortunately, we have never heard of anything on a breaker referred to as "tapes". For taps that is usually used when speaking about a transformer not a circuit breaker.
A6: “Taps” not “tapes”. See PDF – 600 Amp Panel Board for details.
Q7: Could you please confirm breaker specs and tap size. Also, we need to know if the transformer is Copper or Aluminum windings and if Made in USA is required since its being installed at PMRF. Copper is normally used as well on the transformers too.
A7: See PDF – 600 Amp Panel Board for details. Either Copper or Aluminum is acceptable. DFARS Provision 252.225-7000 and Clause 252.225-7001 applies to this solicitation/pending purchase order.
Q8: Line 60 - 600 AMP breaker with dual tapes: is this a separate breaker or does it need to be in the DP Panel?
A8: In the panel. See PDF – 600 Amp Panel Board.
Q9: 600A breaker on line 60. Is that an extra breaker or are they referring to the main breaker in the DP Panel?
A9: That is the main breaker for the panel.
Q10: 300a disconnect. I need to know if you want fusible with neutral or fusible without neutral.
A10: STRONG preference for one with a neutral but they can make it work without the neutral. Please indicate on your quote which type you are quoting.
Q11: Can you verify cut lengths for line 26, 34 & 35?
A11: Line #26 qty of 1330 FT is correct. Line # 34 & 35, the description and qty have changed. See attached updated 1.List of Materials – Revised 5.20.2024.xlsx
Q12. In line #34 and 35 the description is for THWN wire and the link to this item on "platt electric" is for XHHW wire. Are they looking for for THWN wire or XHHW wire?
Line 26 specifies THWN and is 1330ft in a one cut length? The spools are sold 1000'-foot lengths. If it needs to be 1330 continuous feet, then it will have to be a special order.
A12: Line # 34 and 35 need to be THWN. Line # 26 doesn't need to be a continuous run. We can do a spool of 1000' and a cut length of 330' image1.png
