**

Product Information

The WPJBIL-A Weatherproof Junction Box is a wiring accessory that provides IP66 level protection against water and dust ingress. It is designed to be mounted on a clean, rigid vertical surface and is suitable for outdoor use. The product has a load rating of 57A and comes with a rear box and front cover.

Safety Warning

Do not exceed the load rating – 57A.

Installation Instructions

Before commencing work, always isolate the power at the consumer unit/fuse box. Follow the below steps for installation:

The unit should be mounted on a clean, rigid vertical surface suitable to accept screw type fixings. Surface should be reasonably flat as unevenness could cause product damage or affect operation.
Remove Front Cover from Rear Box.
Mount the Rear Box using No.8 screws in all four, or at least two diagonal positions on fixing centres shown. The fixing holes are slotted to enable some rotation adjustment if required. Fit supplied Bungs over all used fixing screw positions to seal aperture recesses.
Make cable entry into Rear Box as required. Only remove the blanking plugs for positions used. Ensure adequate excess lengths of cable for connection to the Terminal Block. Install & seal all cable glands & conduit to manufacturers instructions. To install, remove the blanking plug from the Rear Box, and fit gland or conduit. Ensure the gland or conduit and cable entry are sealed with non-setting sealant.
Position Terminal Block in Rear Box to determine final lengths of cables & cut to suit. Strip outer insulation as required & then trim insulation on individual wires 8-10mm to expose conductor ends.
Connect the wires to the relevant terminals of the Terminal Block.
Tighten terminal screws securely (Do not over tighten).

Safety Instructions:

Please read carefully before installation.

An outdoor location should be chosen ensuring adequate access to a mains supply circuit. The circuit MUST be protected by an appropriate fuse, circuit breaker or RCD (Residual Current Device) in accordance with current IET wiring regulations.
Where conduit is used for cable runs, water condensation MUST be prevented from collecting inside the unit & conduit. Drain holes MUST be drilled out (see Installation Instructions)
If metal conduit is used, earth continuity across the conduit must be maintained using appropriate connections (not supplied).
Where outdoor cable runs occur, ensure cable recommended for outdoor installations is used. In general, rubber insulated cable & plastic M20 cable glands can be used. Alternatively standard flat PVC twin & earth mains cable inside 20mm plastic or metal conduit may be used. Where necessary, SWA (Steel Wire Armoured) cable with metal cable glands should be used. The outdoor use of unprotected flat PVC insulated cable is NOT recommended.
Any earth connections MUST be made & continuity maintained. All bare Earth wires must be sheathed with green/yellow sleeving.

Installation Instructions

Before commencing work always isolate the power at the consumer unit/fuse box.

The unit should be mounted on a clean, rigid vertical surface suitable to accept screw type ﬁxings. Surface should be reasonably ﬂat as unevenness could cause product damage or affect operation.
Remove Front Cover from Rear Box.
For cable entry, decide if conduit is being used & entry positions.
For side, top or rear entry the lowermost drain hole position MUST be drilled out using a 5mm drill. ONLY ONE drain hole position must be drilled. For bottom entry a drain hole MUST NOT be drilled in Rear Box, but a drain hole MUST be drilled at lowermost point of conduit run.
For rear entry, drill/cut the appropriate size hole. For extra sealing protection, channels around knock-out and ﬁxing holes are provided to accept a bead of sealant (not supplied) when ﬁxing to mounting surface.
Note
The drilling of the drain hole or removing a knock-out will reduce the IP rating of the product. Mount the Rear Box using No.8 screws in all four, or at least two diagonal positions on ﬁxing centres shown. The ﬁxing holes are slotted to enable some rotation adjustment if required. Fit supplied Bungs over all used ﬁxing screw positions to seal aperture recesses.
Make cable entry into Rear Box as required. Only remove the blanking plugs for positions used. Ensure adequate excess lengths of cable for connection to the Terminal Block. Install & seal all cable glands & conduit to manufacturers instructions.
To install, remove the blanking plug from the Rear Box, and ﬁt gland or conduit. Ensure the gland or conduit and cable entry are sealed with non- setting sealant.
Position Terminal Block in Rear Box to determine ﬁnal lengths of cables & cut to suit. Strip outer insulation as required & then trim insulation on individual wires 8-10mm to expose conductor ends.
Connect the wires to the relevant terminals of the Terminal Block.
Tighten terminal screws securely (Do not over tighten).
Any earth connections MUST be made & continuity maintained. All bare Earth wires must be sheathed with green/yellow sleeving.
After wiring the Terminal Block, reﬁt the Front Cover to Rear Box, securing using the quick ﬁx fasteners. Turn 150° clockwise with a suitable ﬂat bladed screwdriver to tighten, from 0 to I – DO NOT OVER TIGHTEN.
Once the installation has been completed correctly, replace the fuse/reset MCB (trip), switch the power back on at the consumer unit and test.

Safety Warning

For your safety, this product must be installed in accordance with local Building Regulations. If in any doubt, or where required by the law, con-sult a competent person who is registered with an electrical self certiﬁcation scheme. Further information is available online or from your Local Authority.
Please read carefully and use in accordance with these safety wiring instructions. Before commencing any electrical work ensure the supply is switched off at the mains. Either by switching off the consumer unit or by removing the appropriate fuse or turning off MCB (trip). Wiring should be in accordance with the latest edition of the IET regulations (BS 7671).
To prevent ﬁre hazard always use cable of the correct rating & type for the application.

Warning do not exceed the load rating – 57A

Note
As from 1st April 2004 new colour codes for hard wire installations were introduced.
EARTH = Green/Yellow Sleeving
NEUTRAL = Black (pre Apr 04) / Blue (after Apr 04)
LIVE = Red (pre Apr 04) / Brown (after Apr 04)
If installed correctly BG Electrical Weatherproof products provide an IP66 level of protection, this means that the sealed construction provides a very high level of protection against the ingress of both water & dust.
