Electricity requires a little planning – it’s complicated, potentially expensive and a bit risky – so my plunge into this realm required some study (bought a book and went to the library) and a game plan. The book pictured below was particularly helpful (Amazon) and the section on solar will come in handy down the road.
As I mentioned last post, I have decided to go with 12v lines for my lighting and small appliance needs. There will also be at least two 120v lines for bigger draws.
Two major considerations of wiring a trailer as long as Sparta are length and gauge of wire. The power feed in my trailer was originally located at the rear as evidenced by the circuit breaker box and shore power hook up installed there. This placement required some wire runs of over 60 feet, resulting in more resistance and greater power lost in transmission. When hooked up to a 120v mobile home site power line this may not have been as much of a concern, but for me, anticipating a battery-dependant, solar-fed life, I will have to be more parsimonious with my electricity consumption. So I will place my power center mid-ship. This will achieve two important things – a shorter run between my solar panels and 2 deep-cycle batteries and shorter runs for those circuits running from the batteries forward and aft of center. Pardon the crude, fuzzy diagram below. I couldn’t find my ruler. This is what I am working from – definitely not up to NECA standards.
Gauge of wire is the second important consideration. While I could have just used standard, braided lamp-cord for 12v lines, I chose, instead, to use 14 gauge solid copper wire. This is harder to work with (it is stiff and unwieldy, comparatively speaking) but it will offer less resistance and greater efficiency for my finite power supply.
The pictures below show the specifications of LED light bulbs – a big selling point, “Lumens per Watt”, a recycled junction box wired with new 14 ga. wire. a new, low-profile plastic switch box and the location of boxes (switch and outlets) vis-a-vis my future bed location. That’s all for now. I’m wired on coffee and amped up to work.
