That explains why I like your videos. You know how to explain things plainly enough for the rest of us firefighters to understand!
A key concept when trying to figure out why it's not working. Voltage drop diagnostics would be a great video.
Got to say it again, you're the best teacher out there for this stuff. I'm planning a portable system and you're my go-to!
Hey, Prof.Heinous! I appreciate that. Thanks for watching! 🙂😀
Hey Nate, thank you for serving as a fire fighter in the past.
Woah I had no idea I signed up for Pump Operations with Nate!
🤣😂👍👍🚒🚒
Nate thank you for this video! I am of the belief that the electrical system is the heart of my van build in which I will spare no expense in that category. I will ensure that I will maximize wire gauge for the most optimal voltage set up despite the criticality of the device. thanks so much for sharing this.
Awesome! Glad it helped. Thanks for watching!
Love the videos!
Nate, you are a natural educator! Well done..
Thanks! 🙂🙌
Perfect timing! You're da best!
Hey Phylana Ladd, Thanks so much! Cheers!
Great video. I learned alot today
Glad it was helpful!
Great information. Thanks Don
Great, Thanks!! 👍
Thank you!
Thank you so much for your time. I really value your Wealth of electrical knowledge. I have one question. Is a 20ft PV cable to far from my VICTRON MPPT 100/30 to my solar panel (Grecell 200W PRO)?
WAY good information.
Glad it was helpful. Cheers!
Nice helmet collection in the insulation video. We have a similar one at our Moab House! Do you count the wire length from battery to fuse box for 12v devices?
Nate - A question on the DC to DC charger. Do I need to run a negative wire ? I was planning on just running from the alternator to the DC2DC and take a ground from the frame to the DC2DC. If I do this will have only have 1/2 of the loss over 20’? (I would be using the Victron DC2DC charger 30A)
Firefighters observe so much tragedy others go through and retain it forever in their hearts and minds. I salute all firefighters past, present, and future. Stay strong, but also take care of your own peace of mind.
I appreciate that. Thanks for watching!
Does this also apply for the wiring going from an Inverter to the loads? If I'm correct an inverter will change the voltage from the battery's 12.6V to 110V? So a long wire, lets say from a solar shed across a yard to a house to power a small room, should be no problem with a standard power extension cable?
Hello my friend, amazing 👍 beautiful
Very good Nate, will you be doing a video on DC Ripple?
Thanks! A DC ripple video is pretty low on my list of priorities to be honest. Got lots of other much more important/interesting stuff to dedicate time to.
this is also a good reason for 24v or even 48v systems. voltage drop losses add up quickly...
Hi, I would need some help.
I have 230V to 8V bell transformer and I want to connect an electric bell 8V, trought ca. 20m thin telrphone cable. The problem is that the wire is too long and its loosing the power so that the 8V do not arrive to the bell. What could I do to fix this?
Would it be maybe usefull if I increase the voltage from 8 V to 12V?
Thank You in advance.
Ngl a quick edited version would be nice 😎
Are you volunteering to do the editing or fund the editing? 🫣🤣
@@EXPLORISTlife I’m more of a professional viewer. My editing skills can use some WD.
Electrical friction = resistance
AC power is used for electricity transmission because DC is prone to voltage loss as it is constant.
As you state, voltage loss can result in a device not operating properly. Some devices will draw more amperage (current) as the voltage decreases, which will result in the supplying wire exceeding its amperage rating, thus creating a fire hazard. A properly fused circuit (based on amperage) would then shutdown.
Yep! Another good reason to avoid excess voltage drop.
Voltage drop happens on AC lines too.
Cheers.
🙂👍
What other options are there to make the “light bulb” work other than 4 AWG wire (which will get expensive quickly) I’m just guessing, 24 or 48 volt system for starters?
Great question! For small loads (say...under 10 amps), you could use a DC DC converter to bring the voltage back up to a more appropriate level. This is REALLY dependant on the specific circuit, though.
Powering that light from a 48v battery bank would burn it out nearly instantly because the voltage would be too high.
For larger loads like, say, a 3000w inverter... there really is no good way the inverter would just need to be moved closer to the batteries.
The first 5 minutes also explain why we use AC current and not DC current in normal usage.
And also why most vehicle DC circuits are grounded through the chassis.
We use AC cause it was easier back then to use simple transformers to convert voltages for transmission and distribution.
My inverter/charger will work with lithium batteries.. So I really only want to add about 400 watts of solar(2x200). Do you have a diagram and parts list for something that simple?
Yep! Sure do. Here is a video that teaches you how to use our store so you can find the parts and kits you need for your own specific needs: czcams.com/video/F8nLRWf5ga8/video.html
This video taught me that every 50 feet of firehose requires an increase of 9psi.
But in real world applications, if the nozzle is rated for 100PSI and you pump at 127PSI to overcome friction loss; you are going to have some very pissed off firefighters at the end of the hose attempting to maneuver a hose that has basically turned into a steel pipe. 😂🤣
@@EXPLORISTlifethis is true. I believe ours are rated for 85-100 psi.
DIY CAMPER< Why would the wire gauge cause "DC Ripple" and what is DC Ripple? try to make a video lesson about it
I'll see what I can do! Thanks for watching. 🙂😁
@@EXPLORISTlife Thanks for the help
🍿
Does voltage drop get turned into heat?
Yep!
@@EXPLORISTlife thank you
What is DC ripple?
I'll cover it in a future video. Until then... google is your friend.
Less cable less resistance
Yes indeed, comparing Ur ex-employment fireman, kudos 2 ur services as US Army Infantry vet., n wire length connection 2 fire water hose length, I C that voltage drops at least few elements like dings inside wire or water hose, electrons bouncing around inside wire(s) [!], amongst it, and distance wire length n MOST importantly *THICKNESS wire gauge, {which will transmit voltage (pressure) much faster n reduce resistance or (ohm), which thicker AWG, lower number the thicker wire gauge, compare 2 matric wire gauge, bigger number thicker white gauge {make more sense which we MUST convert everything to matric system thanks to our moron n gutless leaders still NOT implemented!}, is.... In short, thicker wire gauge is the best way to reduce voltage drops between ANY two connection to maintain maximum electricity current, amp or ampere to the other side like bulb, or other electrical devices. VERY well done indeed again! BY the way, just subscribed to Ur channel!
Glad it was helpful. Cheers!
Why not just do what auto makers do and ground the bulb and battery through the metal chasis of the vehicle. That way, you use half the wire.
Using the chassis as a conductor is a great way to end up with grounding problems down the road. We recommend using dedicated wires for all aftermarket devices, components, chargers, etc.
