This connection box is 8x6x4 deep. There is a weidlmuller style terminal blocks inside.The wiring block is off to one side of the box.with 3 # 6s connected to that side.
Feeding the other side of the block is 3 #4 AL thhn conductors. There is no way i can bend the #3 teck conductors to enter the block where the # 6 conductors are now. these terminals are on a din rail type mount.

Now the AHJ wants the mobile home park to replace the connection box to a newer style. My license scope is 200 amp so this would have to be done by another contractor, as it is part of the mobile home park distribution.The customer says the mobile home park will just tell him to move his trailer out.

Every mobile home park that is older than 20 years here all only have 60 amp services available and most wont upgrade.

I asked for the rule # that says i have to upgrade to a 100 amp cable from a 60 amp disconnect(breaker) in service meters
pedestal. b ut he didnt give it to me.

This is the connection box

Not much anyone can do for you when you have one of those.

Stanford Prison Experiment

Give the customer the inspector's name and tell him to write his MLA.

Why would you need 100amps for an old trailer? If the trailer park has 60a
services then the inspector has no issue. If they have 100a services then
mount a 60a outdoor trailer service breaker enclosure at the unit. They are not that expensive.

I found the link to the "Stanford Prison Experiment" quite enlightening. Indeed, we have seen a fair amount of strutting about on this very forum, usually by AHJ's who have grown accustomed to being the 'final word' in their town!

Now, for the trailer power ....

First, I am in the States, and have no knowledge of your Canadian rules. I just find this thread timely, as I have just done my first 'upograde' of a camper/RV space to a trailer space.

Anyway, I thought you'd like to see what I did, in the course of my 'reinventing the wheel.'

Here is the panel that feeds the trailer:



You can see the connection box under the trailer. I was surprised to learn that I needed to run pipe, AND have a connection box; every trailer I have worked on has had the cable directly connected to the pedestal. Sometimes this cable has been directly buried; most often, the cable is simply laying on the ground.

The city explained that they didn't want the trailer connection / set-up crew to have to open the panel.

A close-up of the box reveals the "NSI" type connectors I provided for the set-up crew. (For the detail-oriented, the pigtails ended up somewhat loncer after I finished my panel connections):



As for ampacity: I sized my feed to my load calculations. In this instance I calculated 103 amps, so I provided a 125 amp service. Our code specifies 100 amp service to any 'dwelling.'
