I have a customer with a dryer 220v fed by 2- plug type TL30 fuses. The house has a fused 60 amp service with various 30 amp fused disconnects off to the side for various loads, this being one of them.
Sometime along the way, one side of the dryer 30 amp fused disconnect got very hot. A motor was replaced by the appliance dealer, but she still has problems with the fuse blowing from time to time. Inspection of the fused disconnect revealed the plug type socket got real hot at one time..blackened and fried insulator under the center pin. The fuse on that side continues to get hot and shows a 5-9 voltage drop when in use, (across the fuse). So something needs to be done with the disconnect. Since the customer is going to upgrade the service, yet still needs a dryer, is there any code issue with using a new 100 amp panel only as breaker for the dryer until I get ready for the change over. i.e. I would temporarily mount the panel, feed the mains on the load side of the 100 amp breaker from the 60 amp panel to a 30 amp 2-p breaker, rather than spending the $30+ for another disconnect which won't be needed in a month anyway?
