I would also check the supplier's main fuse size is adequate - may need uprating. If it has a seal on it, the "electrician" shouldn't break it without permission, alternatively, he can ask the DNO to confirm the rating. The diversity for the cable size calculation can be calculated from the...

It's normal to allow 2% VD for feeder circuits, and 4% for lighting and small power - measured at the farthest point in the circuits. Motors are usually designed for 3 or 4% in a running condition, the VD on starting can be 6/7 times this figure for D.O.L. starting, but much less than this for...

I would check that there is ventilation provided on the fittings. Are the fittings suitable for that orientation? What is the recommended lamp size for the fitting? Is there excessive vibration from above? So many questions so little time!

Sounds like a "Mine is Bigger than Yours" contest. This is an industrial or supplier switchroom; and probably a 1600KVA transformer source.

I have inherited this system - Scantronic 9800. I would like to carry out a service but don't know the engineer's code. Is this code necessary to carry out the routine service, to the standard of the security maintenance companies? I only have the user's manual which gives the walk test...

Anyone have recommendations for a commercial door access system, to enable easy operation for a remotely situated person: - e.g. typist to operate. I'm thinking of a wired system, an outdoor station with camera - good resolution and reasonable field of view; and push button or PIR enabled...

I assume that it didn't come with a plug. Contact the supplier for clarification on the 16A fuse requirement; (which is probably to cater for surges on the duty switching). Quote BS1362 for 13A fuses and ask them to check on the time/current curve and whether the 13A fuse is acceptable This...
