Installation Guidance
Gland Entries
On site installation of gland entries The customer may drill plain entry holes in the enclosure providing they are in accordance with the relevant code of practice and are to a recognised standard e.g. BSPP, ET etc. (Parallel threads only). Plain entry holes must maintain the following:

a) The plain hole shall be no larger than 0.7mm above the major diameter of the entry thread.

b) The cable gland or stopping plug is secured internally by a locknut, such that the cable gland or stopping plug will not be dislodged by a 7Nm impact.

c) The enclosure should be maintained at IP66 by the use of a suitable sealing washer under the shoulder of the cable gland.
Mixed Gland Entries For guidance on mixed entries, please refer to the Hawke BoxHUBB enclosure configuratror for assitance with enclosure / entry placement design. A user account will need to be created to access. Alternatively contact Hawke Technical Sales for assistance
Stopping Plugs Stopping Plugs can be instlled into spare entries and shall be held in place by a locknut
 
Terminals
Terminal Wiring It is not permitted to fit more than one conductor per side in rail or direct mounted terminals unless using an insulated Bootlace Ferrule.
Terminal Heat Dissipation To ensure that the maximum temperature as permitted by certification is not exceeded, the dissipated wattage factor formula is used: W = N x F x I² (see enclosure wattage factor). For further details see Enclosure Dissipated Wattage
Intrinsically Safe Circuits For Intrinsically Safe Applications, Exe power terminals can be supplied in blue on request. (Note: The enclosure can either be supplied as Exe or Exia/Ex ib for instrinsically safe applications)
Terminal Linking Linked and mixed terminal arrangements other than those specified in the data tables are available, but the voltage and current figures may be affected to ensure the maximum certified wattage factor is not exceeded. Please contact Hawke Technical Sales for more information.
Earth Terminals The enclosure is provided with an integral internal / external earth stud assembly, but when required, one or more rail mounted earth terminals may be fitted inside the enclosure but the quantity of power terminals shall be reduced accordingly. (Note: power terminals may be used as ‘clean earths’).
Terminal Limitations Terminals for 16mm2 & 35mm2 conductors shall be installed on support rails directly mounted the enclosure base. Stand off pillars are not permisible for these terminal sizes

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.
