We bought a 1967 built bungalow in Ottawa recently and ESA has sent us notice with the following notes. How can we correct this? Do we need to change light fixtures to LED?

OESC 2012 Rule 30-400(1)(c) - The temperature rating of the supply conductors to the luminaire shall not be less than the rating specified on the Luminaire nameplate. Front entrance, hallways, and bedrooms. In addition, please see Bulletin 30-6-7 for more information.

This happens when new light fixtures are installed in a home which has old wiring in it that was only rated for 75 C, new wire is 90 C and since most lights installed today are all rated for 90 C, the only option would be call in a licensed electrical contractor listed with the ESA, let him read the report and do the work that is required to avoid a house fire. Over heating wiring from light fixtures is a huge problem today.

Hi Anita

Rob has explained it very well and yes you need a licensed electrical contractor to review the ESA notice and offer you options and suggestion to rectify this.

If you require further assistance please don't hesitate to contact me as my company only uses licensed ESA approved electrical companies that belong to the Authorized Contractor Program

We also have ESA inspections where required for all work completed in a home.

Sometimes part of the process of replacing wiring and circuits causes drywall damage as drywall holes have to be made to run wires. Part of our services is to repair your home so it looks like the holes were never made.

Just to add to the previous answers...

The old wiring in your home has lower temperature rating then what is installed today. While the electrical safety code does not reach backward and force you to change your wiring, what it does do is it stops you from altering the wiring (such as installing new light fixtures) without meeting today's codes.

As has been pointed out, todays light fixtures are rated for 90*C while your wire is only rated for either 60*C or 75*C. In fact there are two options, if you could actually find a light fixture for a 60 / 75*C rating, you can install them. The second option, which is the more likely, is to install the 90*C rated wire. In this second option there are a number of approaches, so you will need to have an Licensed Electrical Contractor (LEC) come in and provide an estimate for the various options.

Please don't let them tell you that you need your whole house rewired... (unless you want it done). The typical approach in a bungalow would be to junction off the existing light boxes and run a new 90*C tail to the existing boxes. There should be minimal mess to the ceiling. If this was a two / three story it would be a different kettle of fish.

Having said that, this is not inexpensive; having personnel crawl around in your attic, moving insulation, completing repairs and then resetting the insulation and vapour barrier is time consuming with little to no outward appearance of any change.

Thanks John, Glad you pointed out that they should contact a LEC first, so no one else should take your well described info literally and climb in there to do those ever dreaded "hack jobs" that us contractors get called in to repair, and pull a permit for, to do it right for more money safely ;) ...

don't ever skimp on costs for electricians, the cheaper they are, the less likely they are to do it to code!
