I might have been late to the party but I haven't readanywhere that Electrum team had created a wallet for the altcoin. I would be interested to know whether the wallet is still available or it has been abandoned. Please can you share some more insight to support your statement.
As I have mentioned, It's not made by the same developers. But since Electrum is open source, anyone can fork it and make a copy of the software with some tweaks in the code.
I believe this is the original repository:
https://github.com/Electron-Cash/Electron-CashI don't use the wallet but I know it was quite popular back when there was a split and people could've claimed some BCH. So do your own research.
As for the second part of your statement, then I didn't understand exactly what OP was looking for. Does he have some BCH on an exchange that he wants to withdraw to Electron cash? Does he have some funds on Electrum from a very long time ago, and now he wants to claim some BCH? etc.
