One of the most dangers places in your home for electricity is the
ceiling, before entering the ceiling you must turn off all power to the
house, even then a lot of home have the power coming in on overhead lines
that then travel through the roof space to your switchboard, and on rear
accessions these wires can be damage and if you come in contact with them or conductive part that has come in contact with them they
will kill. So with this in mind the best option is turn all power off
including the mains but as the mains often can not be turned off there are
some precautions you can take. I would recommend employing a electrician to
conduct some test for you, The first of these test should be to investigate
before entering the ceiling, the way to do this is to first turn off the
main switch's in the switchboard to remove all power from sub circuits, then
to open the man hole and with a torch have a good look around without
climbing in, see if you can see the mains and where they run, if you can see
all of the mains and they look fine then see if the studs are timber or
steal, if they are steal i would recommend at least testing with a
test pen, at best with a multimeter all electrician's should know how to do
this. Even when all these test have be completed there are no
guarantee that there is 0 chance of electric shock as a cable just being
moved can change this by rubbing through. We are going
to share some stories about electrical accidents in the roof .
A 25 year old Sunshine coast man suffered a fatal electric shock while
working in the roof space of a Victoria Point residential boarding
facility. The man came in contact with a metal structure that hade came in contact
with a live conductor of the lighting circuit which was not on a

Ceiling spaces can pose serious electrical safety risks to homeowners and
tradespeople. Any person entering ceiling spaces needs to take precautions
to minimise the risk associated with electrical cables and equipment and to
let someone know you're entering the ceiling.
TURN THE POWER OFF
Before entering any ceiling space, turn the power off at the main
switchboard and take steps to tape it or label it to stop it being
inadvertently turned back on by another person while you're working in the
Some electrical equipment such as hot water systems or stoves may have a
separate switch. The safest approach is to turn off all the switches and
circuit breakers at the main switchboard.
Even with the power off, avoid contact with electrical cables and equipment
as some cables, such as consumer service lines, may still be live.
Use cordless tools and torches
The use of torches and cordless power tools will avoid the need for power
when in the ceiling space. If power is required, then turn off all circuits
except the circuit supplying the socket outlet you plan to use, but make
sure the circuit is protected by a safety switch. Test the safety switch
before you enter the ceiling.
Other potential hazards to acknowledge
Solar PV systems have DC supply cables which may be live during daylight
Damaged electrical cables or equipment arrange will need repair by a
licensed electrical contractor.
Check that insulation material is not covering any electrical fittings
or equipment, especially down lights.
Other hazards may also need to be addressed, such as, excessive heat,
confined spaces, dangerous vermin, sharp objects or asbestos containing

Venturing into your ceiling space with the power on puts you at serious risk
of electric shock, or worse. If you plan to go into a ceiling space, turn
off all main power switches at the switchboard first.
