Subscribed Demand
The subscribed demand may be assessed by taking account of the loads of all the appliances that are intended to operate simultaneously, as shown in the table below:
| Sum of loads of all the appliances that are intended to operate simultaneously | Subscribed Demand |
|---|---|
| Up to 3,400 W | 3.4 kVA |
| From 3,400 to 6,900 W | 6.9 kVA |
| From 6,900 to 11,500 W | 11.5 kVA |
| From 11,500 to 13,800 W | 13.8 kVA [*] |
| From 13,800 to 20,700 W | 20.7 kVA [*] |
Subscribed Demand / Service Circuit-Breaker Equivalence
For control of the subscribed demand, we will install a service circuit-breaker with a rating, as shown below:
| Subscribed Demand | Service Circuit-Breaker |
|---|---|
| 3.4 kVA | 1x16 A |
| 6.9 kVA | 1x32 A |
| 11.5 kVA | 1x50 A |
| 13.8 kVA | 3x20 A |
| 20.7 kVA | 3x32 A |
