Re: Wiring Diagram feedback

It's roughly 60 amp hours per day. The compressor is a Danfoss BD 35. The thermostat has a 677 resistor so the compressor runs at 2500 rpms.

I see MUCH, MUCH worse diagrams from actual boat builders all the time.

It would be nice if you actually tried to help the OP instead of just slamming his diagram as "completely wrong".

I would challenge you to point out every detail that is "completely wrong" so that he can correct it. Better yet download it into MS Paint and draw in the corrections for him. That would be helpful, bashing his diagram and claiming it is "completely wrong" without also providing detail of where exactly it is "completely wrong" is pretty much of no help to him.

Sadly his diagram skills are actually better than many of the boatbuilders out there.

Let's focus on specifics so we can help each other..
Thanks Maine Sail - for background, I'm a construction guy, training as a carpenter and not an electrician, but I've learned a lot from this forum (and others) and from the tutorials on your awesome site. I appreciate everyone's input on this project and will clean up the diagram when I get back home. Enjoying a day on the boat today, though!

Fair winds everybody.

Re: Wiring Diagram feedback

OK - here's a stab at a cleaned up diagram.....I am still working on details of wiring the alternator regulator into the system - unfortunately the schematic provided with the kit from Electromaax leaves a lot to the imagination!

My AH /day calculations were based on fairly conservative estimates of usage....Would be curious to learn what your average consumption is, if you track that.

My 1985, poorly insulated freezer with spillover frig is biggrr than that. I added an inch of blue foam sheet insul to the freezer and sprayed foam in the rest of the cavities. I draw roughly 120 amps per day, a bit more in toasty conditions. Its an old style seafrost with 2 holding plates. I did add their computer controller. I keep the freezer at 22 degrees near the top and 10 degrees near the bottom.

Again, do you see condensation on any exterior surfaces including the hull? Thats a sign of very poor insul and a shot of foam can really help,even if temporarily.

I don't see condensation on any of the surfaces that are visible, but most of the box is hidden behind other cabinets dividers so it's hard to say for sure. There is a near constant trickle of condensation that goes into the bilge, so there must be some leaky spots at least. Installing additional insulation and reducing the overall size of the box are one of the next steps, and if that doesn't do it I've got to consider either replacing the refrigeration unit or look at an Engel or equivalent.
