thanks Ross, for the complete explanation on fusing and breakers

[@rosslukeman]

Thanks for tuning in Sean!

You do such a great job with these videos! The information I have received is invaluable! Thank you!!

[@rosslukeman]

Thank you Jim! I appreciate the kind words! Great to hear these videos are making an impact-

Thanks for the tip on the pd5000, I was about to cobble something together but that box seems better. Not pretty, but lots of slots.

[@rosslukeman]

Hey Eric, good to hear the PD5000 will work for you. It's definitely a seamless way to make a lot of connections. Thanks for tuning in!

Thanks for posting this Video Ross I did learn that 30 watt shore power has to have a breaker/fuse on incoming power! Ross have you build a system that has both 30 watt and 50 watt shore power systems? In some of your older collection of customers photos who you have build their electrical system you have used multiple sized inverters to lower the energy consumption at night. That is one thing I am interested in knowing more about? Have you considered doing a current video about that? I am interested in a 24 volt system and if I have a two phase system, of two interver chargers that is 3,000 watts? I am trying understand.! In one of your other KZbin videos you talked about 12 volt/24 volt/28 systems.

Hi Hope, thanks for watching, good to hear you got something out of this video! On the 30-amp vs 50-amp, I don't have a video on that yet, and typically those systems do not mix. Although I suppose you could mix them, it would just be unusual. On the dual inverter setup, this has become less relevant as the standby power for the newer inverters is lower, so you can just get by with a larger inverter for everything. In other words, the utility of complicating your system with 2 inverters is diminished these days now that the big inverters don't consume much power in standby. On the 24-volt, two-phase system that sounds like a beast of a system. You may need consulting. That's more than I can handle in a KZbin comment. Thanks for tuning in-

Great information. Keep the videos coming.

[@rosslukeman]

Thanks, glad you enjoyed the video, more to come!

Your presentation needs a dry board with a circuit schematic drawn on it to clearly show how all the components that you showed in this video are connected together to make a complete system.

[@rosslukeman]

I suppose you're right Allen. It sounds like you've seen my Van Power Workshop series. Thanks for tuning in and for sharing your thoughts...

Where did you get 445amp rating for the 4/0 cable? The tables im finding say 170amp copper

[@rosslukeman]

It will need to have a 105 celcius rating to have the higher ampacity rating. Here is one such source, for welding cable: temcoindustrial.com/product-guides/wire-cable-and-accessories/welding-cable

[@jamesalles139]

why not both? 2kW inverter 12v nominal, 333 Amps max peak current draw, I'll use a 400A type T fuse at the battery bank. In series with that, I'll put something like a 175 or 200A DC rated breaker feeding the inverter for generic loads. If I have intentionally down-rated my load to 1800 watts (80% inverter rating), then I might use a 150A DC breaker. The breaker will have a bit of a time delay to tolerate inrush currents, and of course it can be reset if some unexpected load is connected and trips to let me know! thanks for the video

Combined low and high voltage distribution box would be illegal in Australia. Great vid though! Thanks!

[@rosslukeman]

Hi John, thanks for the heads up on that, do you have any breaker boxes you can recommend for Australians?
