One should never screw (change) TT's factory wiring. And if needed, one should install an Inverter to allow one to easily disconnect the inverter area using physical disconnect or perhaps manual off/on switch. Thus, the "Inverter Only" outlets are only active - when you want (need) them active.
With above in mind, simply:
- Connect 12V to 110/120V Invertor (like
- Cobra Inverter box - ) to onboard 12V battery.
Note: Remember to properly size Invertor and its 12V wiring (to battery) as well.
- Inverter can be mounted inside the front storage area or using long 12V "+" or "-" cables, its Inverter box can be within an inside cabinet. Since each RV floor plan is different, one must pick the best install location (base on inner layout).
- Inverter's 110/120V Output Ports are then wired using 110/120 Male Plug and its runs can be 110/120 14/2 house wiring. Simple items at local hardware store.
- 14/2 wiring goes to new (different color) 110/120V outlets. For example, one outlet installed on kitchen area counter. Other outlet installed behind TV Cabinet area. These are "Inverter only" outlets and can be orange color or their covers can be a different color. Thus, clearly showing these 110/120V outlets are "Inverter Only" power.
When Invertor power is needed, simply connect Inverter to battery (or turn on its manual off/on switch - located on Trailer's tongue area), disconnect TV and plug into orange color Invertor Only outlet. And if one wants to make coffee, simply unplug the coffee pot from its normal 110/120 outlet and plug into kitchen counter area orange Invertor Only outlet.
By using above, the Invertor (remember to properly size for max loads) can provide power to Inventor Only outlets (like plugged in Coffee pot or Plugged in TV set) and it can be done without changing factory 110/120V wiring. And when needed, the Inverter can be turned off - using manual off/on switch (or disconnecting from TT's onboard 12V battery). And by using "parallel wiring", one doesn't screw with RV/TT's factory wiring either.
Hope this helps.
