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

    You mention overriding the time clock, have you tried shorting out the time clock to rule it out, in case of any unusual interactions with the load. (failing switching device, or solid state switching device with a minimum load that isn't compatible with low energy lamps).

    Or alternatively, you mention trying different lamps - have you tested it with a regular 60W filament lamp, something guaranteed to draw a reasonable ~0.25A resistive current.
