## Questions & Answers

**Q: Does this product block the upper right circuit from being used? Installation instructions make it look like that is the case, looking to confirm.**
A: Yes, it does block that slot but the slide for the main and gen breakers does also

**Q: Will this work on a Q D braker ?**
A: No the ECMBR2 hold down kit will not work on the QD Breakers

**Q: Can i assume that the ecmbr2 is not a replacement for the ecmbr1 spec'd for the siemens w0816ml1125 [q260 qp-type breaker]?**
A: Correct.  The ECMBR2 is NOT the replacement for a ECMBR1.  If you need a breaker hold down kit for the W0816ML1125CU, you would need to order the ECMBR1.

**Q: Is this required for a 50a breaker used in positions 1 and 3 along with the siemens ecsbpk03?**
A: If you are trying to back feed a breaker then you would use the hold down kit but if you just interlocking 2 breakers like shown in the installation instructions for the ECSBPK03 then no you don't need the hold down kit. https://s3.amazonaws.com/dcc-data-extract/new-delta/asset/Compas/daily/Compas/Instruction%20Sheet%20Quick%20Guide/SIE_IS_ECSBPK03.pdf
