Nice try but that's not code compliant. The code has specific requirements for the GEC including minimum size (e.g. 6 AWG for typical bare copper wire) and connection method (e.g. welded, bolted, etc.) and plug is an allowed method. Also, for SDS, the GEC must be connected at the same point as...
There are several incorrect and confusing statements in the above and I have no interest in addressing them all. As an example, I will just point out that you are misstating what NEC 250.34(B) allows. It only allows a vehicle mounted generator to be ungrounded if it only supplies loads on the...
I agree and my position has always been that code compliance does not necessarily mean safe and vice versa. However, I do want to call out misleading/wrong info especially from companies that can make people think something is code compliant when it's not.
What they told you is misleading and wrong. There is no exception in code for generators that connect to house wiring to be ungrounded. It doesn't matter if the generator is a SDS or not. It also doesn't matter if the generator has GFCI or not. Given the number of code sections they...
Sure but based on what you have shown for your system you also don't have a code compliant installation. Separately derived systems need to have a proper grounding system including a properly sized GEC. This is clearly stated in the owner's manual for the Generac 6852 transfer switch...
Basically, the standard CCS protocol for DC fast charging is being used for discharging because Tesla has a "bug" and not shutting down the charging session when power is actually being discharged (i.e. reverse/negative power flow). It's something that Tesla could easily fix with OTA updates...
The video portion on Tesla appears to show PointGuard taking advantage of the CCS "bug" in Tesla EV's for V2X discharge. Does Signenergy have any agreement with Tesla to ensure continued functionality? If not, what's Signenergy's support policy if Tesla decides to fix the CCS "bug"? This is a...
Not surprised that disconnecting the RS485 ground didn't work. RS485 on systems like this should really be fully isolated electrically. Otherwise it's relatively common to see comms problems due to noise or out of range common mode voltages. One potential fix is to add isolation using an...
True but most (especially the young players) are simply unaware. They get deterred by official looking "warranty void if removed" stickers that are plainly invalid per Magnuson-Moss Warranty Act but manufacturers continue to put them in products.
Yep that's the most practical solution but you might trigger another reminder from someone on the forum about not being code compliant and the safety risks of disconnecting the ground.
No, the truck needs to be connected directly to a separate ground rod. There are many code rules for grounding systems and your AHJ may have additional rules.
My bet is your guess is wrong. It's doubtful that Franklin has a built-in solution for this issue. Frankly, I would be surprised if you can find an electrician that even knows much about the issue with respect to code and has hands-on experience with bonded generators that can't be unbonded...
Transient spikes can easily get coupled via parasitic capacitances that are almost everywhere.
There are many different types of surges/spikes. Whole house surge suppressors are for line to line/netural/ground spikes and typically only suppress voltages that are several hundred volts in...
You would need to make relevant measurements to verify that to be certain. It appears the transfer switch has internal control circuitry to prevent switching to Generator if there is no generator power source while only Utility power is present. This suggests the transfer switch is using...
The voltmeter (and likely the voltage sensor in the truck) has high input impedance due to the designed internal resistance (R) and parasitic capacitances (C) coupled with the parasitic inductances (L) from the long test leads. This means fast transients will get exaggerated (amplified and...
This is expected and adds support to the likelihood of inductive kickback induced voltage transients from switch openings (automatic or manual) when the utility power is present. Remember there is a big inductor at you utility power source (i.e. the secondary winding of your neighborhood power...
Given the cheap voltmeter with its high input impedance (likely > 10 Megohms) and long leads much of what you are seeing is probably greatly exaggerated. When the switch is opened (even manually) there could easily be an inductive kickback enough to induce the observed transients. Frankly, the...
