I bought an inline 30 amp blade fuse for between the battery and the PD4045. Couple questions with this... Is this enough? It is about a 6 inch 12AWG wire with the fuse holder inline. I will connect it between my 10 AWG going between the battery and PD.
30amp will probably be adequate. Looking at your drawing & assuming LED lighting, I dont think you will exceed that
I will also add a master switch... Before or after fuse?
Fuse should be immediately adjacent to the battery, A masterswitch could be placed ahead of, but that would likely be inconvenient placement. (this assuming masterswitch is connected direct to battery, & not utilised as a main DC disconnect on PD4045 ?)
A 30amp inline fuse will be added to the solar wiring.
Great, Remember connected directly adjacent to the battery.
As an aside, Just for fun, Google images of "melted fuseholder".
I hope your fuseholders are up to the task. Sadly alot of them are not.
I bought GFCI receptacles do I need added protection between the shore power inlet and PD?
Its typically not done, GFCI protection is usually installed at the utilization receptacles.
But If you are likely plugging into dodgy/miswired campground receptacle, It would be a good idea. Most effective for this would be a portable equipment GFCI attached to the plug end of your shorepower cable.
Then should I have another wire coming from battery negative to the chassis?
I suggest it. DC Negative grounding is always good practice, & sometimes
required if utilising car charging.
In regards to AC (green) My AC circuits will be routed back to the bus bar in the PD. Then do I route a wire from the bus bar to the chassis as well or is there a conflict having AC and DC directed to the chassis?
Yes ! Always connect trailer chassis to the
grounding bussbar.
DC negative grounding is entirely different thing. It affects nothing to do with equipment grounding conductors.
Last question for now. After reading all the PD setups I am still unsure if after my AC neutral (white) needs to go anywhere but the bus bar in the PD.
All neutral conductors connect to the
neutral bussbar, dont connect anywhere else.
