Square D EDB14035 – Frequently Asked Questions
1) Will a Square D EDB breaker fit in my NF panelboard?
The EDB E-Frame is a bolt-on breaker built for Square D NF lighting panelboards. It bolts to the panel bus rather than plugging on, so it will not drop into a plug-on load center interior. If your panel interior is drilled and tapped for bolt-on E-Frame breakers, the EDB mounts directly.
2) What voltage can a Square D EDB breaker be used on?
480Y/277 V AC is the rated operational voltage on every EDB E-Frame configuration, which is what you want for a 277 V lighting branch circuit off a 480Y panel. It is not a 240 V residential breaker.
3) What wire size do the lugs on the Square D EDB breaker take?
Aluminum lugs on the EDB accept AWG 14 through AWG 6 copper, or AWG 12 through AWG 6 aluminum. Terminal tightening torque is 3.4 N.m for 2.5 to 16 mm2 (AWG 14 to AWG 6) conductors, so a torque screwdriver set to that value covers the full range.
4) Does the Square D EDB come in 1, 2 and 3 pole versions?
All three. Pole count is the selection you make when ordering: single pole for a 277 V lighting circuit, two pole or three pole for multi-phase loads off a 480Y bus. Ordered examples include EDB14035 (1-pole), EDB24035 (2-pole) and EDB34015 (3-pole).
5) Is the Square D EDB breaker UL listed and TAA compliant for a government job?
The EDB carries cULus listing and is TAA compliant, which is what federal, education and healthcare procurement normally asks for on panelboard breakers. Country of origin is Mexico. It is also mercury free.
6) What should I use instead of a Square D EDB for a large feeder that needs a molded case breaker?
The EDB E-Frame is a miniature bolt-on breaker for lighting panelboard branch circuits. For feeder-size molded case protection, the ABB A2A150TT is a three-pole molded case breaker in the A2 Series, and the Eaton Series C K-Frame 6602C72G67 is a 400 A three-pole molded case breaker with an interchangeable rating plug. Both are molded case devices rather than panelboard miniature breakers, so they mount in their own enclosures rather than in a Square D NF panel.
7) Is the ABB ST200M miniature circuit breaker an equivalent to the Square D EDB?
They are different device classes despite both being called miniature breakers. The ABB ST200M is a C-curve breaker listed to UL 1077, which covers supplementary protectors, while the Square D EDB E-Frame is cULus listed as a branch circuit breaker for Square D NF lighting panelboards. Where the drawing calls for branch circuit overcurrent protection in an NF panel, the EDB is the device to use.
8) What is the closest bolt-on miniature breaker alternative to the Square D EDB E-Frame?
The Eaton BAB Series Quicklag thermal-magnetic circuit breaker is also a bolt-on miniature breaker, making it the nearest match in mounting style to the Square D EDB E-Frame, which uses a bolt-on connection. The difference to confirm before swapping is the panel: the EDB is built for Square D NF lighting panelboards at 480Y/277 VAC, so bolt-on geometry alone does not make the two interchangeable in a given enclosure.
9) Can I use an Eaton BAB Quicklag three-pole breaker in place of a three-pole Square D EDB?
Not on a 277-volt lighting circuit. The Eaton BAB-302 Quicklag three-pole thermal-magnetic breaker is a 240 V device, while the three-pole Square D EDB34015 carries a 480Y/277 VAC rating. For a 480Y/277 panelboard the EDB three-pole is the correct choice; the BAB three-pole suits 240 V distribution.
10) Is the Square D EDB breaker rated for HVAC and HID lighting loads?
Yes, the EDB E-Frame is both HACR rated and HID rated, so it can be applied to heating/air conditioning equipment circuits and to high intensity discharge lighting loads in the same panelboard.
11) How do I tell whether a Square D EDB breaker has tripped or was switched off?
The EDB has Visi-Trip local trip indication, a visible indicator at the breaker that shows the device tripped rather than being turned off manually. On a panel of lighting circuits that saves opening up and testing each breaker to find the faulted one.
12) What is the difference between the Square D EDB and the Eaton BAB bolt-on breaker?
Both are bolt-on thermal-magnetic branch breakers, but they are not interchangeable between panels. The EDB E-Frame is rated 480Y/277 V AC for Square D NF lighting panelboards. The Eaton BAB Quicklag bolt-on is an Eaton product, and the three-pole BAB-302 version we carry is rated 240 V, so it belongs on a 240 V Eaton panel, not a 480Y/277 panelboard.
13) Do the Bussmann CBC or CBF breakers substitute for a Square D EDB?
No. The Bussmann CBC Series is a Type I automotive circuit breaker rated 14 VDC and the CBF Series is a Type II automotive breaker; the CBS Series is likewise an automotive family. Those are low-voltage DC vehicle and equipment devices. The Square D EDB E-Frame is a 480Y/277 VAC bolt-on breaker for commercial lighting panelboards, so the two lines do not cross over.
14) I need a breaker with a shunt or undervoltage trip accessory - does the Square D EDB support that?
The EDB E-Frame is supplied as a non-serviceable bolt-on breaker with Visi-Trip local trip indication for troubleshooting. If the application calls for an undervoltage release, that is an accessory of the molded case platforms: the Eaton 10250T undervoltage release is built for the Eaton NZM Series molded case breakers. Specifying a release means moving to that molded case platform rather than an E-Frame panelboard breaker.
15) For a 12-volt DC panel on a service truck, is the EDB or a Bussmann breaker the right part?
Use the Bussmann line. The CBC-B is a Type I automotive breaker with a waterproof stud terminal, and the standard CBC Series is a Type I automotive breaker rated 14 VDC - both intended for DC vehicle circuits. The Square D EDB E-Frame is an AC panelboard breaker rated 480Y/277 VAC and is not a DC vehicle device.
16) Can the Square D EDB breaker be repaired or does it get replaced?
It is a non-serviceable device, so a tripped-and-failed EDB is replaced, not rebuilt. For MRO stock, keep the pole counts and amp ratings you actually have installed on hand.
17) What ambient temperature is the Square D EDB breaker calibrated for?
40 degrees C ambient air temperature. In hotter spaces, such as a closed electrical closet or a roof-adjacent panel, factor that into your load calculation.
18) What are the dimensions of a Square D EDB E-Frame breaker?
The EDB measures 5.66 in by 4.05 in on the published height and depth figures, which is the footprint to check against the gutter space and cover cutout in an older NF interior before you commit to a retrofit.
