Thomas & Betts MS4 – Frequently Asked Questions
1) What voltage is the Thomas & Betts MS4 neutral span clamp rated for?
The MS4 span clamp carries a 35 kV rating, so it covers typical overhead distribution work up through 35 kV class. That rating is the clamp assembly itself; conductor insulation and spacing on your line still govern the install.
2) How many conductors does the MS4 span clamp connect?
Two. The MS4 is built as a two-conductor mechanical connector, which is what you want for tapping or tying a neutral span between a pair of bare conductors rather than bundling three or more runs.
3) Is the MS4 span clamp meant for bare conductor or insulated cable?
Bare. Both the insulation designation and the surface finish on the MS4 are listed as bare, so it lands on bare overhead conductor. If your run is insulated, you would need to strip back to bare metal at the connection point for the clamp to make proper contact.
4) What is the MS4 span clamp made of, and can I use it on aluminum conductor?
Aluminum alloy body. That makes it a natural match for aluminum and ACSR overhead conductor, since you are not introducing a dissimilar-metal joint at the clamp. On copper, an aluminum-bodied clamp puts two dissimilar metals in contact outdoors, which is where galvanic corrosion starts, so most line crews keep it to aluminum runs.
5) What does a neutral span clamp actually do on an overhead line?
It is the mechanical connection that joins the neutral where a span breaks or branches, holding two bare conductors together without a splice or a compression tool. The Thomas & Betts MS4 is that part: a bolted aluminum alloy mechanical connector for two conductors, rated 35 kV, installed with hand tools on the pole.
6) What is the manufacturer part number to order this Thomas & Betts span clamp?
Order it as MS4, Thomas & Betts. One model, no handing or finish options to specify, and it ships as a bare aluminum alloy clamp.
7) Is the Thomas & Betts MS4 sold individually or in a box?
Individually. The MS4 neutral span clamp sells each, so you order the exact count the job needs rather than a carton quantity.
