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...

(( TEMPORARY HOOKUP OF PORTABLE GENNY AT DWELLING, WHICH BONDING JUMPER TO DISCONNECT ? )) Portable generators for temporary power to dwellings such as during power outage after a storm, etc. My subject relates to that. Forum users often discuss parallel path for normal, neutral return...

Hey All, Head scratcher here... I'll start by saying I didn't do it! Really! A neighbor has a Pump>Belts>Generator hydro setup that has recently had substantial re-build work done by two different people. Neither one is an electrician. It's not working. Yet. About four months ago, Local Guy...

I am having a problem with an ATS that is tied in to a corner grounded delta system from utility power. When 1 pump is running, generator works like a champ. When 2 pumps are running, the ATS is constantly switching between utility and generator power. I am new to this kind of wiring system...
