Jim--was there a reason for choosing the E series rather than the M series from Blue [Sea System for the battery switch in the renovation of the primary power distribution on your boat]?

I picked the 5511e as it seemed be the perfect choice for my installation. Its hole pattern also matched the existing holes, which were in a somewhat conspicuous area, so there was a very strong incentive not to make a bunch of new holes. Perhaps an argument could be made that there is a better choice, but I cannot make that argument.

Sorry wasn't looking at it as an argument. I searched the unit and found it offered as either 5511E or 5511M and figured with all your knowledge you would have research both and decided on the "E" model as the best suited

I don't think Blue Sea Systems makes a model 5511M. On that basis, I cannot comment about how it might compare to a model 5511e that I used.

What feature of the M-series do you think would be better than the E-Series? I really am not familiar with the M-series. Is there something about them you think makes them superior to the E-Series?

The M series is the 300A rated product line, while the E series is rated at 350A continuous. While there is not a 5511M product, the 6011 seems to be the model most closely corresponding in function to the E series 5511.

The only advantage of the 6011 I can see from hastily perusing the website is cost, and perhaps compactness. From

6011 m-series $37.95
5511 e-series $50.25

Hope this helps.

Hi Dennis--thanks for the research on the 6011m manual battery switch from Blue Sea Systems. Yes, it looks like the same circuit design as the 5511e. As I said, I picked the 5511e because it fit the existing hole layout for mounting, saving me having to make new holes in the bulkhead to which it is mounted. Size was not a concern. I don't think my electrical distribution system will ever approach 350-Amperes of continuous current, and, if it does, something is very wrong. It would be quite reasonable to use the 6011m switch instead. I think that must be a new addition to the line of manual battery switches by Blue Sea Systems, as I do not recall seeing it before.
