This is my favorite even among others in building trades. My reply, "No we don't have 220v wire but we have 600v and 300v, what soze circuit do you want? "
When I started out, I worked part time in a big box in 1999 -2000. First week on the job I had a customer that was doing a 200a service with the service disconnect outside. I needed to get the customer 4/0 SER but we only had SEU. I sent the customer to the supply house and then asked my department manager where the 4/0 SER was. Ill never forget. He was stocking shelves on a ladder and looked at me like I was nuts and he said "NO" So I asked "Why?" reply...." Ever see a 200 amp sub panel before?....."
I was 22 and from that point I knew what I was dealing with.
