Blackburn FBS4H150A1-12 – Frequently Asked Questions
1) How long is the FBS4H150A1-12 braid, and does that length include the terminal pads?
The cable length is 12 inches. The model designation reads FLEX BRAID 4 7/16H 5/16 X 3 X 12 IN, so plan your bus gap against the 12 inch overall braid dimension and confirm the pad-to-pad centers on your opening before you drill or order.
2) How many bolt holes does the FBS4H150A1-12 have and what size are they?
Four holes, 7/16 inch, which is the standard NEMA pad bolting arrangement for a 4-hole flexible connector. That means it lands on a four-bolt bus pad using 3/8 inch hardware, and you supply the bolts, nuts, and Belleville washers separately; they are not part of the braid.
3) Does the Blackburn FBS4H150A1-12 meet substation switch standards, and is it made in the USA?
It is built to CEI60694 and IEEE/ANSI C37.34-1994, the high-voltage switchgear and air disconnect switch test standards, which is usually what a utility or institutional spec is asking for on a flexible connector. Country of origin is the United States, which matters if your project carries domestic-content requirements.
4) What is a Blackburn FBS4H150A1-12 flexible braid connector used for?
It's a flat, flexible tin-plated copper braid jumper used to carry current between two rigid points that move, vibrate, or expand relative to each other, typical of substation switchgear, bus work, and disconnect terminations. The braid construction lets the connection flex without stressing the bus or the pad. Blackburn builds it to CEI60694 and IEEE/ANSI C37.34-1994.
5) Is the FBS4H150A1-12 copper or aluminum, and can I bolt it to an aluminum bus?
The conductor is tin-plated copper. The tin plating is what makes the dissimilar-metal joint to an aluminum bus workable, but you still want a joint compound rated for the pairing and proper Belleville hardware to hold torque. On a copper bus it bolts up directly.
6) Should I use a flexible braid connector or a solid bus link between two switchgear pads?
Use the braid where the two pads move: thermal expansion on a long bus run, breaker or disconnect operating shock, transformer vibration, or a slight misalignment you cannot shim out. A solid link is simpler and cheaper but it transfers all of that into the pad and the porcelain. This Blackburn part is the flexible flat-braid option, 12 inches long on a 4-hole pad.
7) Is the FBS4H150A1-12 sold individually or in pairs?
Sold each. If you are jumping three phases you need three, and if the job calls for a jumper on both ends of a bus section, double that. Only the single model FBS4H150A1-12 is offered, so there is no length or hole-pattern option to pick.
