Multiple dimmer installation load ratings
To avoid overheating when using more than one dimmer in the same Grid Plus Enclosure it is recommended
that the dimmers are preferentially mounted on the bottom row on 6, 8, 9, 12, 18 and 24 gang enclosures,
before mounting on any other row(s). Also, each dimmer MUST be de-rated and its load adjusted in
accordance with the information provided in Table 3.
The maximum Power/Load figures given in table 3 should not be exceeded, taking due care with different
figures for normal GLS tungsten filament lamps compared with Mains Tungsten Halogen Lamps and Low
Voltage Transformers. Use of the latter is not reccommended.
