Hey all. Happy Early Turkey Day if i don't get back to you by Thursday.
Hope you all have a spectacular week planned.
I have been putting off electrical for a while. Partly because it was the most complete system when I bought the bus and needed the least amount of attention and partly because I love electrical work more than any other and was saving the best for last. (Really I needed to get Sean's advice before he sails off into the sunset
Well, the time has finally come to start planning out the electrical for the coach. First I am going to deal with the DC and I will move onto the AC later. Both systems are up and running it is just a matter of taking what is in place and organizing, simplifying, updating, cleaning up and putting it back together.
For the DC circuits - Overall plan is to keep it simple & safe.
1. A single battery bank for house and starting. I am planning on (4) L-16 AGM Batteries
2. An isolated bus bar for distribution to positive side of the DC Circuit
3. A grounded bus bar (grounded to bus frame) for the negative side of the DC circuit
4. Fuses where needed - Primarily large fuses for the Battery Bank and Alternator circuits - Most of the other circuits have individual fuses for each run
5. There will be one long run of 4/0 cable to the front of the bus (Front DC) to a separate DC panel. This will help with voltage drop to circuits on that side of the bus.
6. The battery bank and inverter will be close within 5 feet.
7. Oversized cable for most runs. For the sake of the board - Not mentioning cable type
8. The leveling system is the "Big Foot" style RV levelers that are each individually fused.
This is my initial layout - Looking for some good feedback and concerns about what I have planned. I am sure I have missed a few things -
My questions are -
1. Do I need to add a voltage regulator - maybe on the battery circuit as that is the only "non" regulated device adding voltage?
2. Should any of these circuits have protection against the amps that the starter is going to throw on the wire? I've seen some devices that "protect" house batteries against the starter but if the starts and house batts are the same - does it make a difference?
3. Is there any other advice or parts/pieces that I should take into consideration?
I have a bunch more questions but wanted to get these simple electrical questions but I'll keep this short and focused for now.
I am sure you will all answer the unasked in replies anyways.
