Installing recessed lighting in the house.

We are going to install 22 pcs of 4" units on the main floor. Or should we go with 6" ones? Especially over the sink and in the dining room.

After the lighting is in place we will put up the drywall and crown molding.

Will the 4" lights look better compared to the 6" ones? Ceiling height is 9 1/2".

Should we have variable spacing between the lights, or equal, is the symmetry mandatory?

I would prefer 6" fixtures. Because the 4" is more suited for accent lighting or a smaller areas.

And what if there are ducts, pipes, wiring or other obstacles in the ceiling. What if I can't fit a housing up there.

How do I know what the code requirements are? Should I check with municipal regulators or call a building inspector? Might I forfeit my home insurance if I do it all by myself?

Another customer emailed me this: Dear Electrician Toronto, I'm renovating father's house and already have installed boxes for pot lights because the ceiling will be insulated. How can I precisely determine the exact position of the openings and cut holes in drywall before it is installed in order to match the drywall holes with those of installed boxes?

The answer is, measure the distance and location of the hole from the adjacent sheet of drywall and mark it on the next sheet to be put up. First, make a smaller hole and then, after the drywall is up, widen it to the correct diameter and position.

Or put some wet drywall compound (mud) around the rim of each box opening/ring, then raise the sheet up into its precise place, and push it up against each opening. Put the sheet on the floor. You will see rings on the back of the drywall sheet reflecting openings' exact locations. Use a hole saw to cut the holes from the face side of the drywall.

I need to insert three cables (six single wires, do not count bare ground conductors) all together into the pot light's junction box. The problem is that the junction box allows maximum of four single wires. What should I do? My answer is - rearrange wires and use no more than two cables with four single conductors per JB.

To hook up your new units to the power source, find a nearest working receptacle (R) or a switch (S) that has both a “hot” and a neutral wires inside its box. Make sure that particular circuit supplying current to the plug or switch is under-loaded. The circuit you choose must not be overloaded by adding the new additional lights to it. Calculate the total wattage of all pre-existing and new items. That wattage divided by 110V gives us the total load in Amps. It should be 13 Amp or less if tapping off of the existing circuit.

To determine a pre-existing load, you first need to shut down a single circuit breaker in the panel that controls your receptacle (R) or switch (S). Then go all over the house and find which lights and plugs are NOT working now. These lights, receptacles and appliances that are dead only when the particular breaker is off, are the existing loads on the receptacle (R) or switch (S) circuit. Assign 150 W to every wall plug. Then add up watts of all currently non working lights, plugs and appliances. Write down the total existing watt number. Add to this number the total wattage of the new proposed items. Do not go over the grand total of 1400 watts for a 15-amp breaker. Otherwise you have to run or fish a new line from the greater distance or all the way from the panel.

Keep in mind that if you use or think you are going to run a portable plug-in heater, you can not utilize that circuit. The heater alone draws 8 to 14 Amps and with other loads that line will trip its breaker, making impossible to engage it together with the lights.

Before doing any electrical work, test every wire with a non-contact voltage tester to make sure they’re NOT hot and then test them with a contact voltage tester before touching. Socket with a bulb could work almost as good as a contact voltage tester until you hit a 240 V pair of wires. You will then need to replace the blown light bulb.

Final piece of advice. Don't do it yourself unless you are absolutely sure you are doing it the right way.

Several pot lights have stopped working one by one even with brand new bulbs at our Lawrence Ave West and Bathurst St. house.

We searched for a pro dealing with this specific problem.

They fixed the pot lights in less than one hour and made them work as new.

A few months later we hired them for a minor house rewiring.

Once again the electricians are committed to high quality service!

I found them to be very professional and helpful. They gave good advice and ideas and recommended affordable solutions.

We would like to take this opportunity to complement these great guys on the efficiency and tidiness of electricians.

We found them here online. They worked efficiently, quietly and were nice to have in one’s home.

We will have no hesitation in recommending you to anybody.
