AlanC2 Posted June 24, 2021 Share Posted June 24, 2021 I'm in the process of switching over from the IOTA Transfer Switch to the ESCO LPT50BRD in our 02 Windsor PST, and while the process has been fairly easy so far, I've run into a problem. In the old IOTA, the ground wires for the Shore Power, Generator, and Panel each had terminals next to the HOT 1, HOT 2, and Neutral connections. The ESCO has a terminal block mounted on the side for the for the chassis ground and other grounds to connect to. Unfortunately, the ground wires for the generator and the electrical panel connections are too short to reach. There is not enough wire to pull more into the box. Is there a "safe" way to extend these wires (using the same size solid copper wire and some kind of connectors) to reach the terminal, or does the ground have to be one continuous wire? Thanks in advance. AlanC2 02 Windsor PST Link to comment Share on other sites More sharing options...
Mark B Posted June 24, 2021 Share Posted June 24, 2021 Alan, I just did mine last weekend. I used the WFCO 57-R because the wire location and layout was the same. There is enough slack if you remove the wire straps, then install them on new transfer before you fasten it down. Here are my before and after.

tmw188 Posted June 24, 2021 Share Posted June 24, 2021 (edited) They make copper split bolts for solid wire or you can use a solid crimp style butt connector which is better looking to give you a clean look. Check the big box stores they have them. I like the fact that they lay out really close. Edited June 24, 2021 by tmw188 1 Link to comment Share on other sites More sharing options...
JDCrow Posted June 24, 2021 Share Posted June 24, 2021 (edited) I was going to use these, but moved my boxes Around and didn’t need them https://www.homedepot.com/p/DryConn-Direct-Bury-Lug-Connector-with-SmartGel-Waterproof-Housing-3-Piece-98105/205072211 Edited June 24, 2021 by JDCrow Link to comment Share on other sites More sharing options...
AlanC2 Posted June 24, 2021 Author Share Posted June 24, 2021 Mark, Thanks for the reply. Unfortunately, the ESCO has you run all the grounds over to one side of the box where the terminal block is. AlanC2 02 Windsor PST 1 Link to comment Share on other sites More sharing options...
tmw188 Posted June 24, 2021 Share Posted June 24, 2021 Is that TS the go to replacement for the IOTA? Link to comment Share on other sites More sharing options...
Guest Dive Dive Posted June 24, 2021 Share Posted June 24, 2021 I just replaced mine with the Esco LPT50BRD and had the same issue. I bought some additional wire of the same gauge and use a heavy copper butt connector to extend. Works excellent. Link to comment Share on other sites More sharing options...

tmw188 Posted June 24, 2021 Share Posted June 24, 2021 So is this Esco TS a popular replacement model? What are other popular models? Link to comment Share on other sites More sharing options...
J Goddard Posted May 18, 2022 Share Posted May 18, 2022 I recently replaced the IOTA transfer switch with the ESCO LPT50BRD transfer switch. Like the OP, the ground wires for the generator and load panel connections were too short to reach the common ground busbar of the new LPT50BRD. In my case, I only needed an extra 3 inches for the ground wires to reach the busbar. Rather than use a splice, I solved this by using the existing slack in both cable runs. The extra length was easily achieved by removing the factory applied foam sealant in the cabinet wall and then pulling the required slack into the compartment. Connections were completed and I applied Great Stuff Fire Block Insulating Foam. Link to comment Share on other sites More sharing options...
