I am renting a portable restroom trailer and the quote states that it has x3 30A 120V on separate breakers. What type of generator do I need? From my understanding the formula to calculate watts is P =V x I so 120V x 30A = 3,600 watts. 3,600x3(breakers) = 10,800 watts. I know that good...

Ok so here is my problem. I am trying to troubleshoot a generator breaker feeding a transfer switch and the gen breaker keeps tripping. Breaker is 1000a @ 480v It will run for at least an hour carrying building load with no problem. After an hour its touch and go. Tripping anywhere from 1hour...

I working in a commercial building in NYC bad we have a generator (Kohler) with multiple ATS switches in different locations throughout the building. My question is can I run the genset control wires in the same conduit as the Ethernet ( Ethernet is for the ats which goes back to the generator...

Good morning everyone. I’ve been looking around for a long time now trying to find a real clean definition of what the classification of a transfer-switch is according to the NEC. I’ve always considered them a cabinet or cutout box but as article 312 is written, these Kohler transfer switches...

Hi all, I recently upgraded my generator from 30A to 50A, and am looking to upgrade my transfer switch setup. My current setup is: 10 circuit transfer switch fed from a 60A breaker in the main panel, with a lockout 30A breaker for the generator feed. Generator feed is an L14-30 inlet on the...

Hello, I understand the title may be not be allowed for safety reasons, but I ask from a brainstorming point of view, in order to understand what can & can't be done from a electrician point of view, not a utility point of view. Here is an outline of what I'm trying to do and why: I...

Hi! I'm a tradesman who got his start pulling wire in a button factory so many years ago. I can still hear the 20 ton presses ringing in my head, punching out belt buckles, metal buttons and various clips. I even learned how to wire metal injection molding machines. Later there was...

I'm having a heck of a time finding an article in the code that says all wires in a circuit need to be terminated in the same panel/enclosure/load panel. As an example, someone installs a back up generator at their house, but it is not a whole house generator, just a 12 circuit panel. The 12...

Is a portable generator (the type typically used by home owners when the power goes out) a separately derived system? Or, is it considered a nonseparately derived system? I have thought it was a separately derived system, but now I am unsure. - When the generator is plugged in, I would say there...

I have a 13Kw 120/240V 60hz diesel generator used as backup power to my home. The AC alternator is a Leroy Somer shunt excited (non PMG) with a #R230 AVR regulating the output voltage. The issue is that the voltage fluctuates by a few volts to where my lights flicker and UPS's trigger alot...

Hi there, Just trying to see if there is anything my neighbour can use his inherited generator for. It's a Chinese 7000W - 3 phase? 380V 50Hz Generator (Senkai brand. I can't even find any information on them. :vs_laugh:) But I do believe since it's got a 3 pole breaker it's a 3 phase...

I'm working on a house with two breaker panels, 200 amp and 110 amp. I put a generator inlet, generator circuit breaker, and interlock on the 200 amp breaker panel. Turns out the furnace is on the 110 breaker panel. I have a photo which hopefully I can attach here. One solution I thought of is...

I'm getting ready to install a transfer switch for a customer and I just want to make sure I am doing this properly. (It's been years since I have installed one of these.) Any help will be appreciated. 1) Do you have to ground the portable generator in any way other than the equipment grounding...
