1. A telephone power isolation system comprisinga housing having a top face;
- at least one transformer having an AC input winding and a plurality of output windings, each said transformer extending through the top face;
a telephone connector having a two pin pair extending through the top face;
electrical connector means including a fuse connecting one side of each output winding to one pin receptacle of said two pin pair and each said face extending through the top face;
electrical connector means connecting the other end of each output winding to the other pin receptacle of the two pin pair;
an LED adjacent each fuse, with each said LED being electrically connected to the electrical connector means connecting the other end of each output winding to the other pin receptacle and arranged to turn on upon breaking of the circuit through said adjacent fuse and extending through the top face;
means carried by the top face to releasably secure a cable connected to the telephone pin connector, and means including a pair of adjustably interconnectable flexible straps; and
each of said transformers and its associated fuses and LED'"'"'s being group together through the top face and independently grouped from each other transformer and its associated fuses and LED'"'"'s.
