multi family dwelling service bond

[strippers&dykes]

does the ground (uffer) and nuetral (grounded conductor)need to be bonded together inside the SES? It has a spot in the SES to bond them but I can't remeber if it needs to be bonded

SES????

SES= Service entrance switch???

Try looking at 250.24

The UFFER and other grounding electrodes must connect to the grounded conductor at any point from the service drop or lateral to the neutral buss of the service equipment.
In the event you have more than one piece of service equipment and the electrodes are not connected prior to that equipment, it must be connected to each SES.

If SES=Service Disconnecting Means (SDM), the actual NEC term, it's as Gus pointed out. What is required at the SDM(s) is a Main Bonding Jumper (MBJ) between Grounded conductor and Equipment Grounding System. If a GEC terminates in an SDM, it can be connected at either end of the MBJ, to the Grounded Conductor or the Equipment Grounding System.
