Dissipated Wattage Factor
The Dissipated Wattage Factor of the enclosures has been established by test to ensure that the maximum temperature as permitted by temperature certification is not exceeded. When terminal quantities greater than those at maximum amps are required (up to maximum physical quantity only) then the current shall be reduced accordingly to remain within the Dissipated Wattage Factor of the enclosure.
Combined Terminal Resistance Factor
This factor is used to determine the number of terminals that can be accommodated within the enclosure without exceeding the Wattage Factor. The Combined Terminal Resistance Factor is the sum of the individual terminal resistance's and the resistance of the cable core equal in length to the enclosure maximum diagonal. (Core Resistance is taken from BS6360). Combined terminal resistance factor.
Wattage to be Dissipated = N x F x I²
N = Number of Terminals. F = Combined Terminal Resistance Factor. I = Maximum Current.
e.g. Number of terminals in a PL630 Enclosure at 20.8 Watts - 10 x 'WDU 2.5' (1=17A), 2 x 'WDU 6' (1=29A), (10 x 0.003035 x 17 ² = 8.77 watts) + (2 x 0.001404 x 29 ²) = 2.36 watts). Total Watts = 8.77 + 2.36 = 11.13 watts.
Therefore this terminal combination is acceptable as the wattage is less than that of the PL630 maximum watts of 20.8 watts.
Note - If a smaller than maximum permitted conductor is fitted into a power terminal, then the smaller conductor resistance must be used when calculating the combined terminal resistance.

Optional Extras
Z-Series Enclosures
The S-Series, EJB range and GRP range enclosures are all available as empty component certified enclosures, allowing for even greater flexibility in their use. If supplied as component certified only, the customer must obtain final certification after fitting their own equipment. Component approved enclosures are denoted by the inclusion of the prefix "Z" i.e. ZS2, ZPL615.
Optional Lid Windows
All enclosure lids for stainless steel enclosures for sizes 2 to 9 in the S-Series and ZS-Series are available with an optional glass viewing window. The windows are manufactured from 6mm thick toughened glass with a 316L stainless steel frame and silicone sponge gaskets which maintain the IP66 rating.
Bespoke Enclosure Design
Should you require a stainless steel enclosure outside of our standard range of products listed, please contact us to discuss the feasibility of producing an enclosure to your requirements.
Drop-in Mounting Plate
The stainless steel enclosures, sizes 1 through 9, are available with an optional "drop-in" mounting plate, making the installation and termination of cabling and associated termination equipment possible. See enclosure accessories for more details.
Internal Document Pockets
The S-Series and ZS-Series enclosures are available with an optional steel internal document pocket upon request. Please contact us for further details.
