Hello All! Thank you for everyone's response. The information has been very helpful. We decided to go with the a single Fuse Holder, that accommodates two types of fuse Carrier's (one for 1 1/4" for the USA and another for 5x20mm for Europe). This way we can use a 5x20mm fuse (IEC127 approved) for Europe and a 1 1/4" fuse (UL/CSA approved) for the USA version of our product.
Thanks again, Rick Loiselle Boston Acoustics Peabody, MA
