The key to doing this is consistency by those who input the points.
If one user uses Elec, another Electric, and a third uses EL, then you might, or might not, have issues because you'll need to know all variations of electric that's being used.
You could do it using the cogo point properties. Create a new point group that'll be dedicated to electric points. Next go to the new group's Properties. On the the Include tab, you can specify that raw descriptions with Elec will be included in this point group. Description with Tele will be excluded and remain in their current point group. You may also use wild card(s) such as *Elec* which will permit the entries Electric and 101Elect to be included in the Elec group.

As an alternative, you can use a numbering system such that Electric entities have Point Numbers from 1001 thru 1999 and Telephone entities are numbered from 2001 thru 2999.
Your point group inclusion criteria would now be based on the With numbers matching instead of With raw descriptions matching. So for electric you can type in 1001-1999. For telephone, a separate group apart from Elec, you can type in 2001-2999. You don't need to have exactly 999 individual entities. As long as the Point Number falls within the range specified, it'll be included.
