I'm a second year student in the IEC and I had no idea what a tap was let alone the rules. I asked my instructor and he didn't explain 90% of what you did. I've spent all week trying to comprehend and learn taps and you explained it so well you taught me everything I need to know in 28 minutes. Thank you!

You explained it very well i have to admit. The way you explain things just sticks i actually retain the information. Thanks.

Thank you, planning on tapping a 400 amp transfer switch with two 200 amp panels and your video confirms that my plans conforms to the NEC.

I know I'm hooked on learning about electrical stuff cause I keep watching.

Well thank you for that. I kept reading the tap rule and other writings about it and was drawing the correct conclusions, but TOTALLY overthinking it and second guessing it. Your real world explanations and explanations of the "why" cleared it up in my mind.

Ryan, your videos are fantastic. Actual technical info and learning on YouTube. Thank you.

Thanks for the excellent video. I work in solar PV installations and we often create a back-fed connection to feeders using Insulated Piercing Connectors (IPC). Although this is a supply connection and not a load connection, we refer to these as "taps" and follow the tap rules for conductor sizing and protection. A typical situation is using an IPC to connect a #6 CU PV output circuit coming from a fused disconnect (60A) to a 4/0 AL feeder that runs from the outside service disconnect to the main breaker of a 200A service panel. We had one inspector tell us that in addition to our PV supply conductor, the portion of the feeder between our "tap" connection and the service panel is considered a "tap" conductor and must comply with tap rules for sizing, length and protection. This becomes an issue when that feeder is SER cable since the portion between the IPC connection and the service panel is not enclosed in raceway. 240.21(B)(1)(3). Does the inspectors interpretation of what is a "tap conductor" seem correct to you in this case?

You're a great teacher! I'm a software engineer who's looking into what a feeder tap is for planned DIY solar + whole house backup hybrid inverter + batteries installation (of course I'll permit it first and inspect before turning on) and your explanation is very clear. Thank you.

Thank you for your service man, I’m a journeymen in Va trying to soak up all this info, your break down is on point. Easy to understand. I’ll recommend you to my people’s.
