Revision as of 09:08, 6 April 2012

Status: 3/23/2012

The various breaker panels near the galley sink are designated:

  • Panel 1: lower, next to the volt meter.
  • Panel 2: upper, outboard to starboard
  • Panel 3: upper, inboard of Panel 2
  • Panel AC: lower, inboard of Panel 1 (all 120v AC breakers)
  • Panel 4: very top

Many of the screws, terminals, and buss bars on these breakers are extremely corroded and some of the breakers will need to be replaced. Note that the breakers on Panel 4 are of a different make and look to be in good shape.

All the breakers have been removed from panels 1, 2, 3, and AC. The breakers are made by Wood Electric Co. Inc. and are part number 112-2NN-101, where NN is the number of amps for which the breaker is rated (for example, a 15-amp breaker is part 112-215-101). Wood Electric no longer exists, but a direct replacement part is manufactured by Potter & Brumfield (Tyco Electronics). The part number is W31-X2M1G-N, where N is again the breaker amperage rating. These can be found at Allied Electronics and other electrical distributors.

The existing breakers will be cleaned and tested. Ones that do not work will be replaced.

A wiring diagram has been started: File:X-dimension breakers.pdf


12-volt Circuits

Here is a list of the 12-volt circuits on the boat.

Circuit Name Orig. Name Orig. Breaker True Amps
Cabin Lights Cabin Lights 30A 1-1  ?
- [1] Cabin Lights (red) 30A 1-3  ?
Foredeck Light Spreader Lts 5A 1-3 1.7A (20W bulb)
Tri-Color Mast Head 15A 1-4  ?
Steaming Light Bow 10A 1-5 0.4A (5W bulb)
Nav Lights Nav Lite Main 15A 1-6  ?
Auto Pilot Auto Pilot 10A 1-7  ?
Nav Lights Aux [2] Nav Lite Aux 15A 2-1  ?
Compass [3] Compass 10A 2-2  ?
Fresh Water Pump F.W. Pump 15A 2-3  ?
- [4] Salt 15A 2-4  ?
Nav. Inst. Nav. Inst. 30A 2-6  ?
Nav. Subpanel [5] Radio Phone 30A 3-1  ?
Propane Stove 5A 3-2  ?
Fuel Pump [6] F. Pump 30A 3-3  ?
Footlights [7] Footlights 15A 3-4  ?

Notes:

1. Do we need a separate breaker for red lights? probably not, since many of the red lights are on the "white" circuit.

2. Do we need auxilary nav lights? If they work, perhaps we'll keep them.

3. Compass light circuit might be combined with lights for instrument panel

4. We will probably not keep this.

5. The Nav station subpanel circuits might be moved to the main breaker panels.
