blowing 50 amp time delay fuses

It`s been very hot lately. I.E. over 100 degrees. I blew a fuse on my service to my compressor last friday. Now the same side blew again yesterday. Around 10 days later. Any ideas?

You can take an amp draw at the compressor to see if its pulling high amps, also chk all line voltage conections from panel to load side of contactor.

Also check the fuse clips for tightness, ie- how well they grasp the fuse.

What size fuses are specified on the compresser namplate?

Also, check the voltage at the contactor with and without the compresser running. Maybe your utility's voltage is running low in the hot weather? That will increase motor amps.
