No, Table 220.55 in the National Electrical Code (NEC) is specifically for dwelling units in a multifamily dwelling with three or more dwelling units that use electric ranges, wall-mounted ovens, counter-mounted cooking units, and other household cooking appliances. Section 220.53 is for dwelling units with electric ranges, wall-mounted ovens, counter-mounted cooking units, and other household cooking appliances.Here's why you wouldn't use Table 220.55 instead of 220.53 for an 8-unit building: 220.53 applies to any number of dwelling units

Section 220.53 provides a demand factor of 75% for the total connected load of four or more appliances fastened in place, in dwellings with electric ranges, wall-mounted ovens, counter-mounted cooking units, and other household cooking appliances.

Table 220.55 provides demand factors for specific circumstances

Table 220.55 provides several options for calculating demand factors for household cooking appliances, based on the number of units and the ratings of the appliances. It is often more beneficial to use Table 220.55, but it is not required.

In Summary

In a multifamily building with 8 units, you have the option to use Table 220.55 to calculate the load for the cooking appliances. If you do not use Table 220.55, then you must use 220.53.

It is always recommended to consult with a qualified electrician or electrical engineer to ensure compliance with all applicable codes and regulations in your specific jurisdiction. They can help you determine the most appropriate method for calculating the service load for your building. Flag for review
