Hi - I have a small spot light out the back of my house that has a
broken casing. So I wish to replace the entire unit. Problem here is
that I have little electrical experience.
Now I have taken the unit off the wall and can see 2 wires going into
the existing light (blue and brown). So all I really need to do is
unscrew the wires and screw them into the new unit.
Before this point I have turned off the power at the switch box and
also ensured the light switch is turned off (just in case).
To be safe, I'm just checking here because as far as I can see as long
as the power is completely off I should have no problem completing this
small task without electrocution.
Do i really need to use an insulated phillips head screwdriver for this
So i wear rubber gloves or something?
any other tips?
I think it was bellamy firstname.lastname@example.org who stated:
That's all you really need to do. If the wires that were there match
the wires that ARE there, you're good to go.
What I do is leave teh power ON at the light switch, just to be sure
that the circuit I turned off was the one at the light I wanted off.
I think you're OK . . . .
One more thing you can do is to short all the wires in the box
together before you actually touch anything metal. That will reassure
you that there are no live wires left anywhere.

Thanks. Do you reakon I'd need to use insulated tools for this sort of
When you say "short all the wires in the box" do you mean tap the 2
together and see if it sparks? How safe is this if you use your fingers
insulation to do this?
Is there any chance once you turn off the power that a charge is still
in the wires?

A good idea, it it would not save you if the lamp burned out at just the
wrong time, which once happened to me. Now I turn it off, check to see if
the lamp is off, turn it back on and recheck to make sure it is on then turn
it off again. I did not get hurt, but I did get a shower of sparks. :-)
yes because the previous homeowner ran another circuit wire nearby
which is still live. with the level of expertise being low, then
increase the safety level by turning off the MAIN breaker. electricians
have helpers with cellphones and flashlight; they know how to keep
water from coming in thru the wall around the fixture, know what
adapter plate and stainless steel screws to choose, how to select a
photo-eye fixture for your job, how to measure for the hot voltage on
one of the wires to go to the center light bulb terminal of the light
socket, and whether to recommend a GFI outlet nearby for your
convenience in the backyard. they can recommend wiring repairs and
updates to you and give you written estimates for them.

Tag the switch something like "do not turn on - work in progress" Lock the

Have an extra person around to get help or have a cell phone in you pocket
for a 911 call. My scaffold collapsed a few years ago and I landed on my

have been nice.
If you are gonna trash the old liht fixture I would twist the two
wires together just in case there was a capacitor in it and someone
( maybe your kiddos ) dont pick it up and get their bell rung

An electrical "sniffer" is a handy tool for the unsure.
They only cost a couple of bucks and can identify a live wire without
touching it. Yes, tools can fail, but they can also really help make
sure that everything is off.
