30 Amp DIY Wiring Updates for 4000W Heater

I have been wiring for a long time now. Never used "anti shorts" I just use flex fittings that does not require them. YMMV.

Did you forget the anti-short on the heater itself?

Oh god... I've bought two houses, and both were catastrophes in their own special ways. In one house the downstairs was wired correctly, but the upstairs was 50/50 reversed load & neutral - it also had 4 pairs of 3-way switches, and not one pair functioned correctly - and finally, indoor GFCI outlets were used in outdoor locations without any weatherproofing. All easy stuff to fix in the first couple days, but it was disconcerting. The other house had structural problems, so out of scope for ElectroBoom... and quite a bit more expensive to fix.

After hiring a few licensed, bonded, and insured contractors, and then reading up and learning code and having to fix their work, I now don't hire them any more.

knob and tube wiring?

happy new year Mehdi! Hope you had happy holidays with the family

My house was built in 1936, we are renovating our kitchen right now. Finding all kinds of fun electrical errors.

Yes, in Ontario I believe it really needs to be inspected but many people don't. But you run two risks. 1) a fire if you don't know what you are doing, and 2) if there is ever a fire due to wiring the home insurance might not cover it.

I love the brutal honesty around "sharing knowledge". 😁

Your codes are weird, I'm used to the socket amp is a maximum rating, not a minimum… and if something is defined as fixed load I can reduce the wire size as long as a short on the end will trip the breaker immediately. I say I can because your codes are weird, if you follow our codes NEK 400 your get an shitty installation, but safe, it can always be done better than the codes

Sound like a double fault! We don't worry about double fault!

oh wow. don't know if my antishort red thingie comment was even worth saying! then, you did all this. for me? aw.

You shouldn't use the plastic connector inside the panel. The point of the metal connector is the bond the armour in case there is a break in the armour between each end. Then if there is a short to the armor and you touch it, you will experience yet another zap.

In Canada don't we have to get any new electrical wiring inspected? .. that or have an electrician do the job.

Yup! This is why I always hire a licensed, bonded, and insured contractor for this sort of thing. BEZAN-LIKE-O!!
