Can Anyone "shed some light.."

ThatDoesntLookRight

Evening All,

I have an installation, and need a little assistance:

Client has 6 bollards in a row on a garden circuit, which is digital Time-Clock controlled.

The supply is buried SWA loops which as usual loops in and out of each. The lamp-holders are Bayonet Caps, in new condition, (no loose springs!) and new lamps.

There is a little 4-Amp(?) bladed fuse in-line of the Live of each fitting, these are all checked / new.

There is a confirmed 240v Live to Neutral, And (L-to-E) at each set of pins / terminals, within each bollard; however a lamp only operates inside of one, -the central fixture.

Any thoughts or wisdom?

nb, As part of the process, we've tried new lamps, swapped the lamps around, (still only the one same bollard lighting up) overridden the time clock, and verified Neutral connections through-out. The current at the lamp-holders also seems consistent at each fitting.

Many TIA

    Asking the silly questions first, the bollards don't have a built-in photocell or other controls do they?

    Hi Andy,

    - No inline controls, sneaky photocells on bollards or side of the building etc. They are switched through this time clock though and that crossed my mind, as a possible compatibility issue.

    Mike I have to pop back to swap a light elsewhere on the building (unrelated) and can re-measure the Amps, the but as you said at a couple of Watts per lamp (maybe 13watt each?) I'm at the low end of the testers tolerances.

    maybe I should re-wire all the gubbins in 10mm Al singles Thinking   Wink

    How about (temporarily) connecting individual bollards using a length of flex, with a 13A plug attached plugged into a looong extension lead?

    If the bollard lights on the temporary connection then at least you have a starting point - you know the bollard is good so it must be a supply issue.
