Wiring Fans Into Lighting Circuit

[fishheadbarandgrill]

I'm interested in mounting two Caframo 757 fans onto the headboard in the vberth (2011 R29). I would mount them close to each of the 2 lights so that I can tie into their wiring. Has anyone else done this? I can't find anything in the Albums or forums. There isn't a lot of wiring to play with and a splice won't push into the existing hole in the headboard. I'm thinking I might need to hone out the hole with a wood file.

Thanks,

Might need to run a home run back to the fuse block running both may heat that up? I ran my fans back to the block worked perfectly

I did consider that. The fan motor is rated at .4A and I've replaced all my lighting with LEDs. I think I would be okay based on what I understand of the wiring schematic. They have a 10A breaker with 16 AWG wires. Tell me about how you ran your wires back to the fuse block. Did you run it back to the DC panel and tie into the Accessory breaker?

Ran it back to the fuse block on our 29 that is in the head and wired direct to the block been great

I've not seen a fuse block in our head, Where is it located? I don't see on in our electrical schematics either.

We have a 17 29 cb head has an access door to the helm dash

Look behind the mirror in the head for the “fuse block”.

If you switched over to LED bulbs you definitely should be fine with that arrangement.

Bob, I don’t see any reason why you couldn’t stick with your original plan, unless it’s not physically possible to make the splice.

If you do run it home to the fuse box, there are some open fuse slots available, at least there are on my boat. If nothing is open you can piggyback onto an existing circuit. Just make sure you pick one with a fairly robust fuse. I used the circuit that powers the v-berth 12v outlet (which I don’t use) - it had a 30a fuse.

I did the calculations. My bulbs are rated at 1.5W. The fan draws 0.4A which is 4.8W. Considering the bulbs where at least 10W halogens... I haven’t confirmed that yet and I do still have them onboard... I’m well under 10W at each light fixture.

I will have to look behind the mirror. I’m curious if there’s a fuse or terminal block there. There’s no fuse block listed in the schematics.

I installed a Caframo fan in the V berth. I removed one of the lights and replaced it with the fan.( I installed the removed light in the pilot house)The light circuit is labeled V berth on the fuse panel with a 15 amp fuse installed. The light wiring is 14 ga wire. The circuit is more then adequate to run the fan with the lights.I installed one fan it is sufficient in the V birth area for us. You have a larger area so the second may be needed. We normally run the fan on low and it moves the air enough to make sleeping very comfortable when on the hook. I installed a 3 amp fuse replacing the 15amp fuse. To protect the fan. I have had no issues with this install two seasons of use.

Thanks Brian. I don’t think my lights are fused. I have a breaker for each lighting circuit. Great idea to replace the light with a fan. I think my wiring is 16awg based on the schematics.
