That means you can't use any inverter higher than 3800 watts without getting a main panel upgrade or a "line side tap". The highest inverter output current acceptable for 20-amp breakers would be 16 amps, since 16 X 1.25 equal 20. supply side tap n ac disconnect: 60a fused, (2) 40a fuses, 240v nema 3r, ul listed, (if required by utility) supply side tap connection option (e)main breaker to house 240v, 200a/2p (v.i.f) (e)main service panel, 200a rated, 240v (shall be field verified) g bond #6 awg cu to new or existing ground rod (3)#6 thwn-2 in 3/4" conduit comply with ...

Line side tap solar diagram. Line-side tap connection: This method requires that the wires from the inverter are connected to the service wires on the line side of the circuit breaker. This connection is very rarely allowed for residential systems but is increasingly common in commercial systems. SUPPLY (OR LINE) SIDE CONNECTION INTERCONNECTION REQUIREMENTS EXCERPT Rev. 09/27/19 A Supply Side Connection (SSC), also referred to as a Line Side Tap constitutes a new service as defined by the National Electric Code (NEC), and is subject to all applicable NEC requirements and/or requirements adopted by the Authority Having Jurisdiction. 7.5 Is the Manufacturer's approval for load side tap or UL (or other NRTL) field evaluation performed? 7.6 For solar ready panels, is the appropriate tap model used in accordance with the panel manufacturer? 7.7 For solar ready panels, is the PV Source breaker sized according to the manufacturer's specifications? Re: Backfed breaker or Line side tap? I see one disadvantage of the line side tap and that is now I need to add overcurrent protection on the line between the inverter and the grid to protect the conductors between the PV meter and the inverter from potential overcurrent caused by a short on the AC side of the inverter.

NEC Article 690.64(A) allows a Line‐Side AC connection to busbars, conductors, or lugs at any point between the customer's side of the utility meter, and the service disconnect. Many folks call this a "line‐side tap", which leads to confusion with the "10‐foot tap rule" and Article 240.21(B). Note: this wiring diagram is simply an example. Diagrams may vary. SMA rapid shutdown box mounted under solar modules RS SMA rapid shutdown push button disconnect switch (mounted outside and adjacent to the service panel) #18 AWG THWN, 600V rated wire, ½" EMT Hi all, I'm a homeowner trying to understand my future solar install as much as possible. I'm going to be installing solar while at the same time making some changes to the service at my home to power a new detached shop. My plan is to upgrade my 200a service to 400a. The house already has a 200a panel and the shop will get a new 200a panel. My thought was to put a new load center between the house and the meter/load center combo, as a place to connect the solar inverters, as well as a fut... December 2014 #7.

In your diagram you have a tap. But, by the way, if you just add a backfed breaker to a panelboard on the load side of the service disconnecting means, then it is a load side connection, but it is probably not a tap. Our online solar software allows you to generate a single-line diagram of your residential PV design, along with a cover page, site plan, placards, attachment plan, attachment detail, fire safety plan, code-validated electrical calculations, and equipment data sheets. The LST2 diagram on the last page provides a partial detail of the tap connection. The position of the junction box will vary depending on the panel configuration and if the service is from overhead or underground to the meter. Line Side Tap 3 (LST3) - Line Side Tap connection installed to the bus between the meter and service main breaker.

The line-side tap is technically an extension of the service conductors since there is no overcurrent protection other than that provided in the PV system disconnecting means. In the 2017 NEC, the rules have been reversed. Now, If the PV system is connected to the supply side of the service disconnecting means as permitted in 230.82(6), the PV ...

In systems where inverter output connections are made at feeders, any taps shall be sized based on the sum of 125 percent of the inverter(s) output circuit current and the rating of the overcurrent device protecting the feeder conductors as calculated in 240.21(B)."

Have a 200a panel with a 200a breaker and will be adding 14.5kW of solar. My main panel can only accommodate 240a of supply. I can either backfeed panel and reduce the main breaker to 175a, or connect my solar to the meter with a line side tap. 175a is probably adequate, most of my heating is currently gas. Installer is fine using either option, but said line side tap is a little easier. He said I can monitor production/consumption the same way in either case. Any other pros or cons?

Option #3: Line Side Tap. An increasingly common solution is known as a Line Side tap, a.k.a. Supply Side tap. This work is usually done by a licensed electrician. The main breaker box is completely bypassed, and a fused AC Disconnect is used to connect the inverter to the grid between the utility meter and the main breaker box. This removes ...

Line side tap would only be needed if you wanted more than 50A breaker for PV. Or, if you want to feed grid directly into your inverter, and be able to switch the whole house main panel to output of inverter, using it as UPS for the entire house. Simple way to go is what you were thinking. 50A breaker feeds Outback.

An installer said that to me. I have a 200amp breaker and the installer said that if my system is greater than 8kW AC then I need a line side tap. Is this true? I am assuming the installer isn't lying. He did say if I did go above that number then I need a line side tap vs not having one, and adding one is $1500. Does it really cost that much to add that?

For you guys who do a lot of solar, when you tap the service conductors in the service disconnect for your solar disconnect, is that disconnect considered a service disconnect and required to be grouped with the main? I'm getting different answers from different solar installers. Code references would be cool but I know you guys are busy. I would consider it a service disconnect but there could be an exception that I don't know about

7. Residential "solar ready" service panels designed with an alternative energy (customer generation) interconnection circuit breaker on the line side of the main breaker is allowable. "Solar ready" panels must be EUSERC approved and have factory installed labels showing location and ratings of the generation source 8.

01-25-2021, 01:55 AM. A line side tap will not accommodate any off grid operation BUT a simple Grid Tie would work, when the grid goes down - your inverter goes down. To use any battery, you need to be able to isolate parts of your house from the grid. Many hybrid inverters have small transfer relays in them, but if they are feeding a line side ...

This panel design constitutes a line-side tap. A separate set of busbars, rated at 60 amps, is supplied for connecting to an inverter with a set of breakers. That set of busbars is connected directly to the load side of the meter socket before the main disconnect, bypassing the main busbars altogether.

See diagram of current setup and potential 50A CT placement. The inverter app shows me solar generation, the emporia app shows my total household load, but I can't see how much of that load is being addressed by the Utility vs. my solar system because of the line side tap. So far, I have been waiting a day and using the Utility website to see ...

When installing a tap on the line side of the service disconnect for your pv disconnect, do you always group the new disconnect with your main? If not could you provide the nec articles that allow you to have it remote from the main? Hopefully this post doesn't get rejected because it is so short

Hey all, I have 90A Backfeed headed for a 200/200 single phase panel. Seems like a dead ringer for an LST. I'm curious what the cost adders look like, obviously an AC Combiner and a readily accessible disco - but will the utility company whack me $5000 to come on site and shut the service off during install? Edit: Also need a PV specific meter

Line Side Tap. Governing Code(s): NEC 705.12(A), 705.31. A line side tap (or supply side tap) refers to a connection between the meter and main breaker. This is the preferred method of interconnection for solar installers as it is the most straight forward and requires the least amount of calculations.

A supply side tap is a connection that is made to the busbars or conductors on the line or utility side of the main service disconnect. The line side tap the simplest way of interconnection when installing a PV system that exceeds the 120% rule.
