Thanks yes I think the other side is to increase the arth rods to get a better earth at the distribution panel and the enclosure box (100meter seperation mostly overhead 240V)
The SMS unit is a Cyplex Packetiser.
In one sense it could be trned off The packetiser will be on battery...
This area is large water reservoir tanks and I data log level and send 96 readings in one SMS to graph the daily level changes. Their are alarm points so they do not overflow as these tanks are in the jungle up top of a hill or backend of a small mountain (gravity water feed method)

Hello waross
Thank you I need to clarify I guess this is always the problem on a post second guessing.
OK the systemn is in a secure enclosure (padlock box) and the ELCB is being tripped regularly during storms. The system is a low current example a GSM I/O device and Paperless recorder and...
I am trying to identify if there exists a circuit breaker capable of being reset remotely.
In my application theres not always somebody around to reset the C/B manually i.e overnight after a lightning strike.
I'm talking regarding mains power.
I am aware of auto resetting types for automotive...
....of course mobile phones have been banned from the site?
Who hasn't got a camera integrated mobile phone these days?I wouldn't expect them to be a PAL or NTSC device.
A camera detector bought would become a wasted investment.
Also with a mobile, no need to worry about sneaking in all the...
I need to connect 2 reading devices (loads) to the one loop.
(Load 1)is a 0~5volt load not sure maybe 250ohm external resistor across the analogue channel input of the ECO T paperless recorder.
(Load 2) The other is a 0~4volt load over an external 200ohm 1% resistor on the analogue input of...
